Let's divide 686624 by 39
We want to figure out the number of times 686624 can be divided by 39.

Going ahead to step 1:
6 divided by 39 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 39

Let's proceed to step 2:
When dividing 68 by 39, we get 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 29 after subtracting 39 from 68.
Include the next digit (6) from the dividend after 29, then repeat: 296 / 39

On to step 3:
296 divided by 39 is 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 17.0
If we take 273 away from 296, we end up with 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 39

Moving on to step 4:
When dividing 236 by 39, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 176.0
The remainder is 2 after subtracting 234 from 236.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 39

Let's proceed to step 5:
The number 39 fits into 22 0 times, leaving a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 1760.0
The remainder is 22 after subtracting 0 from 22.
Fetch the next digit (4) from the dividend, attach it to 22 and continue: 224 / 39

On to step 6:
If we divide 224 by 39, we get 5 and a remainder of 29.
The next digit of our result is 5. 
Result so far: 17605.0
If we subtract 195 from 224, we 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.

Moving on to step 7:
39 goes into 290 7 times with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 17605.7
Subtracting 273 from 290 leaves us 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.

Advancing to step 8:
The number 39 fits into 170 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 17605.74
Subtracting 156 from 170 leaves us 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.

Let's proceed to step 9:
39 can be fit into 140 3 times, resulting in a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 17605.743
If we subtract 117 from 140, we 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.

Let's proceed to step 10:
39 goes into 230 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 17605.7435
The remainder is 35 after subtracting 195 from 230.
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 11:
When dividing 350 by 39, we get 8 with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 17605.74358
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.

Going ahead to step 12:
39 can be fit into 380 9 times, resulting in a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 17605.743589
Deduct 351 from 380 and we're left 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.

Let's proceed to step 13:
39 goes into 290 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 17605.7435897
Subtracting 273 from 290 leaves us 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.

Moving on to step 14:
The number 39 fits into 170 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 17605.74358974
The remainder is 14 after subtracting 156 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 17605.74358974 with a remaining 1.4e-08.
