76812456 ÷ 122 
We want to figure out the number of times 76812456 can be divided by 122.

Step 1:
7 divided by 122 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 122

Let's proceed to step 2:
When dividing 76 by 122, we get 0 with a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Grab the next digit (8) from the dividend, add it to 76, then carry on: 768 / 122

Advancing to step 3:
122 goes into 768 6 times with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 732 from 768 leaves us with 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 122

On to step 4:
If we divide 361 by 122, we get 2 and a remainder of 117.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
If we subtract 244 from 361, we get 117.
Fetch the next digit (2) from the dividend, attach it to 117 and continue: 1172 / 122

Step 5:
1172 divided by 122 is 9 with a remainder of 74.
Record the quotient 9 as the next digit in the result. 
Result so far: 629.0
Deduct 1098 from 1172 and we're left with 74.
Take the next digit (4) from the dividend and append it to 74, then repeat: 744 / 122

Step 6:
The number 122 fits into 744 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 6296.0
If we take 732 away from 744, we end up with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 122

Moving on to step 7:
If we divide 125 by 122, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 62961.0
If we take 122 away from 125, we end up with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 122

Moving on to step 8:
122 can be fit into 36 0 times, resulting in a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 629610.0
Subtract 0 from 36 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
The number 122 fits into 360 2 times, leaving a remainder of 116.
The number 2 becomes the next digit in our result. 
Result so far: 629610.2
If we subtract 244 from 360, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 10:
122 goes into 1160 9 times with a remainder of 62.
Put 9 as the next digit of the answer. 
Result so far: 629610.29
If we subtract 1098 from 1160, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
122 can be fit into 620 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 629610.295
Deduct 610 from 620 and we're left 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.

Step 12:
100 divided by 122 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 629610.295
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.

Step 13:
122 goes into 1000 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 629610.29508
If we subtract 976 from 1000, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
240 divided by 122 is 1 with a remainder of 118.
The next digit of our result is 1. 
Result so far: 629610.295081
Subtract 122 from 240 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 15:
122 can be fit into 1180 9 times, resulting in a remainder of 82.
Write down 9 as next digit of the result. 
Result so far: 629610.2950819
Subtracting 1098 from 1180 leaves us 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.

Going ahead to step 16:
122 can be fit into 820 6 times, resulting in a remainder of 88.
Use 6 as the next digit of our solution. 
Result so far: 629610.29508196
If we take 732 away from 820, we end up 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.

The final result is 629610.29508196 with a remainder of 8.8e-08.
