76978915 divided by 122 
Our goal is to divide 76978915 by 122.

Let's proceed to 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
Subtracting 0 from 7 leaves us with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 122

Moving on to step 2:
122 goes into 76 0 times with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Take the next digit (9) from the dividend and append it to 76, then repeat: 769 / 122

Going ahead to step 3:
122 goes into 769 6 times with a remainder of 37.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 732 from 769 and we're left with 37.
Append the next digit (7) from the dividend to 37 and continue with: 377 / 122

Advancing to step 4:
377 divided by 122 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Deduct 366 from 377 and we're left with 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 122

Moving on to step 5:
122 can be fit into 118 0 times, resulting in a remainder of 118.
Record the quotient 0 as the next digit in the result. 
Result so far: 630.0
Deduct 0 from 118 and we're left with 118.
Fetch the next digit (9) from the dividend, attach it to 118 and continue: 1189 / 122

Step 6:
1189 divided by 122 is 9 with a remainder of 91.
Put 9 as the next digit of the answer. 
Result so far: 6309.0
Subtract 1098 from 1189 to get 91.
Take the next digit (1) from the dividend and append it to 91, then repeat: 911 / 122

Let's proceed to step 7:
If we divide 911 by 122, we get 7 and a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 63097.0
The remainder is 57 after subtracting 854 from 911.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 122

Step 8:
When dividing 575 by 122, we get 4 with a remainder of 87.
Use 4 as the next digit of our solution. 
Result so far: 630974.0
If we take 488 away from 575, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 9:
If we divide 870 by 122, we get 7 and a remainder of 16.
The next digit of our result is 7. 
Result so far: 630974.7
Subtract 854 from 870 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
122 can be fit into 160 1 times, resulting in a remainder of 38.
The next digit of our result is 1. 
Result so far: 630974.71
Subtract 122 from 160 to get 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 11:
The number 122 fits into 380 3 times, leaving a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 630974.713
Subtract 366 from 380 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
140 divided by 122 is 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 630974.7131
Deduct 122 from 140 and we're left with 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 13:
122 can be fit into 180 1 times, resulting in a remainder of 58.
Put 1 as the next digit of the answer. 
Result so far: 630974.71311
Deduct 122 from 180 and we're left 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.

In conclusion, the division gives 630974.71311 with a balance of 5.8e-05.
