631677 divided by 42 
Let's see how many times 42 fits into 631677.

On to step 1:
42 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 42

Going ahead to step 2:
63 divided by 42 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 42 from 63, we get 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 42

Going ahead to step 3:
When dividing 211 by 42, we get 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 1 after subtracting 210 from 211.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 42

Going ahead to step 4:
16 divided by 42 is 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 150.0
Subtract 0 from 16 to get 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 42

Moving on to step 5:
42 can be fit into 167 3 times, resulting in a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 1503.0
If we take 126 away from 167, we end up with 41.
Bring next digit (7) of the dividend behind the 41 and repeat the process: 417 / 42

On to step 6:
The number 42 fits into 417 9 times, leaving a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 15039.0
If we take 378 away from 417, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
If we divide 390 by 42, we get 9 and a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 15039.9
The remainder is 12 after subtracting 378 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
120 divided by 42 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 15039.92
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
When dividing 360 by 42, we get 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 15039.928
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
When dividing 240 by 42, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 15039.9285
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
If we divide 300 by 42, we get 7 and a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 15039.92857
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
The number 42 fits into 60 1 times, leaving a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 15039.928571
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
If we divide 180 by 42, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 15039.9285714
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 15039.92857142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 15039.92857142, with a leftover of 3.6e-08.
