Let's divide 659683 by 39
We want to divide 659683 by 39.

Advancing to step 1:
The number 39 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 39

On to step 2:
39 goes into 65 1 times with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 39 from 65 leaves us with 26.
Bring next digit (9) of the dividend behind the 26 and repeat the process: 269 / 39

Going ahead to step 3:
39 can be fit into 269 6 times, resulting in a remainder of 35.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 234 from 269 and we're left with 35.
Grab the next digit (6) from the dividend, add it to 35, then carry on: 356 / 39

Let's proceed to step 4:
The number 39 fits into 356 9 times, leaving a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 169.0
Deduct 351 from 356 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 39

Going ahead to step 5:
The number 39 fits into 58 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1691.0
The remainder is 19 after subtracting 39 from 58.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 39

Step 6:
If we divide 193 by 39, we get 4 and a remainder of 37.
Record the quotient 4 as the next digit in the result. 
Result so far: 16914.0
If we subtract 156 from 193, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
If we divide 370 by 39, we get 9 and a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 16914.9
If we take 351 away from 370, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
39 goes into 190 4 times with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 16914.94
Subtracting 156 from 190 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
The number 39 fits into 340 8 times, leaving a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 16914.948
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
39 goes into 280 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 16914.9487
The remainder is 7 after subtracting 273 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 11:
The number 39 fits into 70 1 times, leaving a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 16914.94871
Subtracting 39 from 70 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 12:
39 goes into 310 7 times with a remainder of 37.
The next digit of our result is 7. 
Result so far: 16914.948717
The remainder is 37 after subtracting 273 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 13:
The number 39 fits into 370 9 times, leaving a remainder of 19.
The next digit of our result is 9. 
Result so far: 16914.9487179
Subtract 351 from 370 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 14:
When dividing 190 by 39, we get 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 16914.94871794
Deduct 156 from 190 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 16914.94871794, with a leftover of 3.4e-08.
