We look at the division of 15697 by 39 
We're looking to find how many times 39 goes into 15697.

Step 1:
1 divided by 39 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 39

Going ahead to step 2:
39 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 39

Moving on to step 3:
156 divided by 39 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 0 after subtracting 156 from 156.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 39

On to step 4:
9 divided by 39 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtract 0 from 9 to get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 39

Going ahead to step 5:
39 goes into 97 2 times with a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 402.0
The remainder is 19 after subtracting 78 from 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 6:
The number 39 fits into 190 4 times, leaving a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 402.4
The remainder is 34 after subtracting 156 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
If we divide 340 by 39, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 402.48
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
When dividing 280 by 39, we get 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 402.487
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.

Moving on to step 9:
70 divided by 39 is 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 402.4871
Deduct 39 from 70 and we're left 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.

Going ahead to step 10:
If we divide 310 by 39, we get 7 and a remainder of 37.
The next digit of our result is 7. 
Result so far: 402.48717
If we subtract 273 from 310, 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.

Advancing to step 11:
When dividing 370 by 39, we get 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 402.487179
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.

On to step 12:
190 divided by 39 is 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 402.4871794
If we take 156 away from 190, we end up 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 13:
39 goes into 340 8 times with a remainder of 28.
The next digit of our result is 8. 
Result so far: 402.48717948
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 402.48717948, with a leftover of 2.8e-08.
