We look at the division of 101851 by 39 
We're looking to find how many times 39 goes into 101851.

On to step 1:
39 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 39

On to step 2:
If we divide 10 by 39, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 39

Step 3:
When dividing 101 by 39, we get 2 with a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 78 from 101, we get 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 39

Step 4:
The number 39 fits into 238 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtract 234 from 238 to get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 39

On to step 5:
45 divided by 39 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 261.0
Subtract 39 from 45 to get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 39

On to step 6:
If we divide 61 by 39, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 2611.0
Deduct 39 from 61 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
39 goes into 220 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 2611.5
If we take 195 away from 220, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
If we divide 250 by 39, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 2611.56
The remainder is 16 after subtracting 234 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
160 divided by 39 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 2611.564
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
The number 39 fits into 40 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 2611.5641
Deduct 39 from 40 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
39 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 2611.5641
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
39 goes into 100 2 times with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 2611.564102
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
The number 39 fits into 220 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 2611.5641025
The remainder is 25 after subtracting 195 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 14:
39 can be fit into 250 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 2611.56410256
Subtracting 234 from 250 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 2611.56410256 with a remainder of 1.6e-08.
