We're dividing 155868 by 39 
We're looking to find how many times 39 goes into 155868.

Advancing to step 1:
If we divide 1 by 39, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 39

Advancing to step 2:
15 divided by 39 is 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 39

Step 3:
155 divided by 39 is 3 with a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 117 from 155 and we're left with 38.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 39

Moving on to step 4:
When dividing 388 by 39, we get 9 with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 351 away from 388, we end up with 37.
Bring next digit (6) of the dividend behind the 37 and repeat the process: 376 / 39

On to step 5:
If we divide 376 by 39, we get 9 and a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 399.0
The remainder is 25 after subtracting 351 from 376.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 39

Step 6:
The number 39 fits into 258 6 times, leaving a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 3996.0
Subtracting 234 from 258 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
240 divided by 39 is 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 3996.6
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
When dividing 60 by 39, we get 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 3996.61
Subtract 39 from 60 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
If we divide 210 by 39, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 3996.615
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
When dividing 150 by 39, we get 3 with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 3996.6153
Deduct 117 from 150 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 11:
The number 39 fits into 330 8 times, leaving a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 3996.61538
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
39 goes into 180 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 3996.615384
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
The number 39 fits into 240 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 3996.6153846
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
The number 39 fits into 60 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 3996.61538461
If we take 39 away from 60, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 3996.61538461 with a balance of 2.1e-08.
