631718 divided by 39 
Our goal is to divide 631718 by 39.

Step 1:
6 divided by 39 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
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 / 39

Going ahead to step 2:
The number 39 fits into 63 1 times, leaving a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 39 from 63 to get 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 39

Let's proceed to step 3:
241 divided by 39 is 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 234 from 241 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 39

Let's proceed to step 4:
39 can be fit into 77 1 times, resulting in a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 161.0
Deduct 39 from 77 and we're left with 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 39

Let's proceed to step 5:
If we divide 381 by 39, we get 9 and a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 1619.0
Subtract 351 from 381 to get 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 39

Advancing to step 6:
The number 39 fits into 308 7 times, leaving a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 16197.0
Subtracting 273 from 308 leaves us 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.

Step 7:
When dividing 350 by 39, we get 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 16197.8
If we subtract 312 from 350, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 8:
The number 39 fits into 380 9 times, leaving a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 16197.89
Subtracting 351 from 380 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 9:
39 can be fit into 290 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 16197.897
Subtract 273 from 290 to 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.

Advancing to step 10:
39 can be fit into 170 4 times, resulting in a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 16197.8974
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.

Advancing to step 11:
140 divided by 39 is 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 16197.89743
Subtract 117 from 140 to get 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 12:
230 divided by 39 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 16197.897435
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 13:
39 goes into 350 8 times with a remainder of 38.
The next digit of our result is 8. 
Result so far: 16197.8974358
If we subtract 312 from 350, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 14:
39 can be fit into 380 9 times, resulting in a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 16197.89743589
If we take 351 away from 380, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The quotient of the division is 16197.89743589, and the remainder is 2.9e-08.
