77699747 divided by 122 
We want to divide 77699747 by 122.

Going ahead to step 1:
122 goes into 7 0 times 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 (7) of the dividend behind the 7 and repeat the process: 77 / 122

Let's proceed to step 2:
The number 122 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Append the next digit (6) from the dividend to 77 and continue with: 776 / 122

Moving on to step 3:
122 can be fit into 776 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 732 from 776 to get 44.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 122

On to step 4:
122 goes into 449 3 times with a remainder of 83.
The next digit of our result is 3. 
Result so far: 63.0
If we take 366 away from 449, we end up with 83.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 122

Going ahead to step 5:
839 divided by 122 is 6 with a remainder of 107.
Put 6 as the next digit of the answer. 
Result so far: 636.0
Subtract 732 from 839 to get 107.
Take the next digit (7) from the dividend and append it to 107, then repeat: 1077 / 122

On to step 6:
1077 divided by 122 is 8 with a remainder of 101.
The number 8 becomes the next digit in our result. 
Result so far: 6368.0
Deduct 976 from 1077 and we're left with 101.
Take the next digit (4) from the dividend and append it to 101, then repeat: 1014 / 122

On to step 7:
The number 122 fits into 1014 8 times, leaving a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 63688.0
If we take 976 away from 1014, we end up with 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 122

Going ahead to step 8:
When dividing 387 by 122, we get 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 636883.0
If we subtract 366 from 387, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 9:
122 can be fit into 210 1 times, resulting in a remainder of 88.
Put 1 as the next digit of the answer. 
Result so far: 636883.1
Subtracting 122 from 210 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.

Moving on to step 10:
When dividing 880 by 122, we get 7 with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 636883.17
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.

Moving on to step 11:
260 divided by 122 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 636883.172
The remainder is 16 after subtracting 244 from 260.
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 12:
If we divide 160 by 122, we get 1 and a remainder of 38.
The next digit of our result is 1. 
Result so far: 636883.1721
Deduct 122 from 160 and we're left 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 13:
122 goes into 380 3 times with a remainder of 14.
The next digit of our result is 3. 
Result so far: 636883.17213
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.

Moving on to step 14:
The number 122 fits into 140 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 636883.172131
Subtracting 122 from 140 leaves us 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.

Advancing to step 15:
122 goes into 180 1 times with a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 636883.1721311
Subtract 122 from 180 to get 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 final result is 636883.1721311 with a remainder of 5.8e-07.
