We divide 885131 by 21
We're looking to find how many times 21 goes into 885131.

On to step 1:
8 divided by 21 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 21

Let's proceed to step 2:
21 can be fit into 88 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 84 from 88 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 21

On to step 3:
The number 21 fits into 45 2 times, leaving a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Deduct 42 from 45 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 21

Moving on to step 4:
When dividing 31 by 21, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 421.0
If we subtract 21 from 31, we get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 21

Let's proceed to step 5:
21 goes into 103 4 times with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 4214.0
Subtract 84 from 103 to get 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 21

Advancing to step 6:
If we divide 191 by 21, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 42149.0
Subtract 189 from 191 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 21, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 42149.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
21 goes into 200 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 42149.09
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 42149.095
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
The number 21 fits into 50 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 42149.0952
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
When dividing 80 by 21, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 42149.09523
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 12:
21 goes into 170 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 42149.095238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
21 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 42149.095238
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
21 goes into 200 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 42149.09523809
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

In conclusion, the division gives 42149.09523809 with a balance of 1.1e-08.
