We look at the division of 78651287 by 122 
We want to figure out the number of times 78651287 can be divided by 122.

Going ahead to step 1:
When dividing 7 by 122, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 122

Advancing to step 2:
The number 122 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
If we take 0 away from 78, we end up with 78.
Take the next digit (6) from the dividend and append it to 78, then repeat: 786 / 122

Advancing to step 3:
122 goes into 786 6 times with a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 732 from 786 and we're left with 54.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 122

Let's proceed to step 4:
When dividing 545 by 122, we get 4 with a remainder of 57.
Write down 4 as next digit of the result. 
Result so far: 64.0
Subtracting 488 from 545 leaves us with 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 122

Going ahead to step 5:
If we divide 571 by 122, we get 4 and a remainder of 83.
The next digit of our result is 4. 
Result so far: 644.0
Subtracting 488 from 571 leaves us with 83.
Grab the next digit (2) from the dividend, add it to 83, then carry on: 832 / 122

Let's proceed to step 6:
The number 122 fits into 832 6 times, leaving a remainder of 100.
Write down 6 as next digit of the result. 
Result so far: 6446.0
The remainder is 100 after subtracting 732 from 832.
Grab the next digit (8) from the dividend, add it to 100, then carry on: 1008 / 122

Let's proceed to step 7:
The number 122 fits into 1008 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 64468.0
Subtract 976 from 1008 to get 32.
Include the next digit (7) from the dividend after 32, then repeat: 327 / 122

Advancing to step 8:
If we divide 327 by 122, we get 2 and a remainder of 83.
The number 2 becomes the next digit in our result. 
Result so far: 644682.0
Deduct 244 from 327 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 9:
The number 122 fits into 830 6 times, leaving a remainder of 98.
Write down 6 as next digit of the result. 
Result so far: 644682.6
If we subtract 732 from 830, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 10:
When dividing 980 by 122, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 644682.68
Subtract 976 from 980 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
40 divided by 122 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 644682.68
If we take 0 away from 40, we end up 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.

On to step 12:
If we divide 400 by 122, we get 3 and a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 644682.6803
If we subtract 366 from 400, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
If we divide 340 by 122, we get 2 and a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 644682.68032
The remainder is 96 after subtracting 244 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 14:
When dividing 960 by 122, we get 7 with a remainder of 106.
Record the quotient 7 as the next digit in the result. 
Result so far: 644682.680327
Deduct 854 from 960 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 15:
122 can be fit into 1060 8 times, resulting in a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 644682.6803278
Deduct 976 from 1060 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 16:
The number 122 fits into 840 6 times, leaving a remainder of 108.
The next digit of our result is 6. 
Result so far: 644682.68032786
The remainder is 108 after subtracting 732 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final result is 644682.68032786 with a remainder of 1.08e-07.
