We look at the division of 78629301 by 122 
We want to divide 78629301 by 122.

Let's proceed to step 1:
7 divided by 122 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 122

On to step 2:
When dividing 78 by 122, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 122

Going ahead to step 3:
When dividing 786 by 122, we get 6 with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 732 from 786 to get 54.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 122

Moving on to step 4:
122 can be fit into 542 4 times, resulting in a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtract 488 from 542 to get 54.
Grab the next digit (9) from the dividend, add it to 54, then carry on: 549 / 122

Step 5:
122 can be fit into 549 4 times, resulting in a remainder of 61.
Write down 4 as next digit of the result. 
Result so far: 644.0
Deduct 488 from 549 and we're left with 61.
Fetch the next digit (3) from the dividend, attach it to 61 and continue: 613 / 122

Advancing to step 6:
If we divide 613 by 122, we get 5 and a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 6445.0
If we take 610 away from 613, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 122

Step 7:
The number 122 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 64450.0
The remainder is 30 after subtracting 0 from 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 122

Going ahead to step 8:
122 can be fit into 301 2 times, resulting in a remainder of 57.
Use 2 as the next digit of our solution. 
Result so far: 644502.0
Subtracting 244 from 301 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 9:
122 can be fit into 570 4 times, resulting in a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 644502.4
Deduct 488 from 570 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 10:
The number 122 fits into 820 6 times, leaving a remainder of 88.
The next digit of our result is 6. 
Result so far: 644502.46
Subtracting 732 from 820 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 11:
122 can be fit into 880 7 times, resulting in a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 644502.467
If we subtract 854 from 880, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
260 divided by 122 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 644502.4672
Subtracting 244 from 260 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.

On to step 13:
122 can be fit into 160 1 times, resulting in a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 644502.46721
Subtracting 122 from 160 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
122 can be fit into 380 3 times, resulting in a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 644502.467213
The remainder is 14 after subtracting 366 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 15:
When dividing 140 by 122, we get 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 644502.4672131
Subtract 122 from 140 to 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.

Let's proceed to step 16:
122 goes into 180 1 times with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 644502.46721311
Subtracting 122 from 180 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The quotient of the division is 644502.46721311, and the remainder is 5.8e-08.
