Let's divide 631739 by 39
Let's see how many times 39 fits into 631739.

Step 1:
When dividing 6 by 39, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 39

Advancing to step 2:
If we divide 63 by 39, we get 1 and a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 39 from 63 leaves us with 24.
Bring next digit (1) of the dividend behind the 24 and repeat the process: 241 / 39

Step 3:
The number 39 fits into 241 6 times, leaving a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 234 from 241, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 39

Step 4:
39 goes into 77 1 times with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
If we take 39 away from 77, we end up with 38.
Include the next digit (3) from the dividend after 38, then repeat: 383 / 39

Advancing to step 5:
If we divide 383 by 39, we get 9 and a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 1619.0
The remainder is 32 after subtracting 351 from 383.
Bring next digit (9) of the dividend behind the 32 and repeat the process: 329 / 39

Let's proceed to step 6:
329 divided by 39 is 8 with a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 16198.0
The remainder is 17 after subtracting 312 from 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
39 goes into 170 4 times with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 16198.4
Subtract 156 from 170 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
39 goes into 140 3 times with a remainder of 23.
The next digit of our result is 3. 
Result so far: 16198.43
Subtracting 117 from 140 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
If we divide 230 by 39, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 16198.435
If we take 195 away from 230, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 10:
If we divide 350 by 39, we get 8 and a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 16198.4358
Subtracting 312 from 350 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
When dividing 380 by 39, we get 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 16198.43589
Subtract 351 from 380 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 12:
290 divided by 39 is 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 16198.435897
Deduct 273 from 290 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 13:
39 can be fit into 170 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 16198.4358974
Deduct 156 from 170 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
The number 39 fits into 140 3 times, leaving a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 16198.43589743
Deduct 117 from 140 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 16198.43589743, with a leftover of 2.3e-08.
