We divide 631066 by 42
Our goal is to divide 631066 by 42.

Let's proceed to step 1:
42 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 42

Step 2:
If we divide 63 by 42, we get 1 and a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 42 from 63 and we're left with 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 42

On to step 3:
If we divide 211 by 42, we get 5 and a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 210 from 211, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 42

Going ahead to step 4:
When dividing 10 by 42, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 150.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 42

On to step 5:
The number 42 fits into 106 2 times, leaving a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 1502.0
Deduct 84 from 106 and we're left with 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 42

Step 6:
42 goes into 226 5 times with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 15025.0
Subtract 210 from 226 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
42 goes into 160 3 times with a remainder of 34.
The next digit of our result is 3. 
Result so far: 15025.3
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
340 divided by 42 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 15025.38
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
42 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 15025.38
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
If we divide 400 by 42, we get 9 and a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 15025.3809
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
If we divide 220 by 42, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 15025.38095
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
100 divided by 42 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 15025.380952
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
When dividing 160 by 42, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 15025.3809523
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 14:
42 goes into 340 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 15025.38095238
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 15025.38095238, with a leftover of 4e-09.
