We're dividing 42126909 by 888 
Let's see how many times 888 fits into 42126909.

Moving on to step 1:
If we divide 4 by 888, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 888

On to step 2:
42 divided by 888 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 888

Let's proceed to step 3:
When dividing 421 by 888, we get 0 with a remainder of 421.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 421 after subtracting 0 from 421.
Take the next digit (2) from the dividend and append it to 421, then repeat: 4212 / 888

Going ahead to step 4:
888 can be fit into 4212 4 times, resulting in a remainder of 660.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 3552 from 4212 leaves us with 660.
Include the next digit (6) from the dividend after 660, then repeat: 6606 / 888

On to step 5:
If we divide 6606 by 888, we get 7 and a remainder of 390.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtracting 6216 from 6606 leaves us with 390.
Take the next digit (9) from the dividend and append it to 390, then repeat: 3909 / 888

Going ahead to step 6:
If we divide 3909 by 888, we get 4 and a remainder of 357.
Write down 4 as next digit of the result. 
Result so far: 474.0
If we take 3552 away from 3909, we end up with 357.
Bring next digit (0) of the dividend behind the 357 and repeat the process: 3570 / 888

On to step 7:
When dividing 3570 by 888, we get 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 4744.0
Subtract 3552 from 3570 to get 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 888

Let's proceed to step 8:
If we divide 189 by 888, we get 0 and a remainder of 189.
Use 0 as the next digit of our solution. 
Result so far: 47440.0
Deduct 0 from 189 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Let's proceed to step 9:
1890 divided by 888 is 2 with a remainder of 114.
Record the quotient 2 as the next digit in the result. 
Result so far: 47440.2
If we subtract 1776 from 1890, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 10:
The number 888 fits into 1140 1 times, leaving a remainder of 252.
Use 1 as the next digit of our solution. 
Result so far: 47440.21
If we take 888 away from 1140, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 11:
2520 divided by 888 is 2 with a remainder of 744.
The number 2 becomes the next digit in our result. 
Result so far: 47440.212
The remainder is 744 after subtracting 1776 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

On to step 12:
If we divide 7440 by 888, we get 8 and a remainder of 336.
Record the quotient 8 as the next digit in the result. 
Result so far: 47440.2128
If we take 7104 away from 7440, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 13:
If we divide 3360 by 888, we get 3 and a remainder of 696.
The number 3 becomes the next digit in our result. 
Result so far: 47440.21283
Deduct 2664 from 3360 and we're left with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Advancing to step 14:
888 goes into 6960 7 times with a remainder of 744.
The number 7 becomes the next digit in our result. 
Result so far: 47440.212837
If we take 6216 away from 6960, we end up with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Let's proceed to step 15:
888 goes into 7440 8 times with a remainder of 336.
Record the quotient 8 as the next digit in the result. 
Result so far: 47440.2128378
Deduct 7104 from 7440 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 16:
The number 888 fits into 3360 3 times, leaving a remainder of 696.
Record the quotient 3 as the next digit in the result. 
Result so far: 47440.21283783
Subtract 2664 from 3360 to get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

The final outcome is 47440.21283783, with a leftover of 6.96e-07.
