We look at the division of 8157739 by 105 
Our goal is to divide 8157739 by 105.

Let's proceed to step 1:
105 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 105

Let's proceed to step 2:
If we divide 81 by 105, we get 0 and a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 105

Advancing to step 3:
If we divide 815 by 105, we get 7 and a remainder of 80.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 735 from 815 to get 80.
Fetch the next digit (7) from the dividend, attach it to 80 and continue: 807 / 105

On to step 4:
105 can be fit into 807 7 times, resulting in a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
If we subtract 735 from 807, we get 72.
Bring next digit (7) of the dividend behind the 72 and repeat the process: 727 / 105

Moving on to step 5:
727 divided by 105 is 6 with a remainder of 97.
Write down 6 as next digit of the result. 
Result so far: 776.0
Subtract 630 from 727 to get 97.
Take the next digit (3) from the dividend and append it to 97, then repeat: 973 / 105

Advancing to step 6:
When dividing 973 by 105, we get 9 with a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 7769.0
Subtract 945 from 973 to get 28.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 105

Going ahead to step 7:
If we divide 289 by 105, we get 2 and a remainder of 79.
Record the quotient 2 as the next digit in the result. 
Result so far: 77692.0
Subtracting 210 from 289 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 8:
If we divide 790 by 105, we get 7 and a remainder of 55.
The next digit of our result is 7. 
Result so far: 77692.7
Deduct 735 from 790 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
If we divide 550 by 105, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 77692.75
If we subtract 525 from 550, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
105 goes into 250 2 times with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 77692.752
If we subtract 210 from 250, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
105 goes into 400 3 times with a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 77692.7523
If we take 315 away from 400, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 12:
If we divide 850 by 105, we get 8 and a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 77692.75238
If we take 840 away from 850, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
When dividing 100 by 105, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 77692.75238
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 14:
If we divide 1000 by 105, we get 9 and a remainder of 55.
Use 9 as the next digit of our solution. 
Result so far: 77692.7523809
Subtracting 945 from 1000 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 15:
105 can be fit into 550 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 77692.75238095
If we take 525 away from 550, 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.

After the division, we end up with 77692.75238095 and a remainder of 2.5e-08.
