We look at the division of 78121292 by 110 
We want to figure out the number of times 78121292 can be divided by 110.

Going ahead to step 1:
110 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 110

Let's proceed to step 2:
The number 110 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 110

Moving on to step 3:
110 goes into 781 7 times with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 770 from 781 and we're left with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 110

Step 4:
112 divided by 110 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 71.0
Subtract 110 from 112 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 110

On to step 5:
If we divide 21 by 110, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 710.0
Subtract 0 from 21 to get 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 110

Step 6:
If we divide 212 by 110, we get 1 and a remainder of 102.
The next digit of our result is 1. 
Result so far: 7101.0
If we subtract 110 from 212, we get 102.
Bring next digit (9) of the dividend behind the 102 and repeat the process: 1029 / 110

On to step 7:
If we divide 1029 by 110, we get 9 and a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 71019.0
If we take 990 away from 1029, we end up with 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 110

Step 8:
110 can be fit into 392 3 times, resulting in a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 710193.0
If we take 330 away from 392, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
110 goes into 620 5 times with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 710193.5
If we subtract 550 from 620, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
If we divide 700 by 110, we get 6 and a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 710193.56
Subtracting 660 from 700 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
110 can be fit into 400 3 times, resulting in a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 710193.563
Subtract 330 from 400 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 12:
If we divide 700 by 110, we get 6 and a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 710193.5636
The remainder is 40 after subtracting 660 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
The number 110 fits into 400 3 times, leaving a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 710193.56363
If we take 330 away from 400, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 14:
110 goes into 700 6 times with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 710193.563636
If we subtract 660 from 700, 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.

Moving on to step 15:
110 goes into 400 3 times with a remainder of 70.
The next digit of our result is 3. 
Result so far: 710193.5636363
If we subtract 330 from 400, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 16:
110 goes into 700 6 times with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 710193.56363636
If we subtract 660 from 700, 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.

The final outcome is 710193.56363636, with a leftover of 4e-08.
