We divide 99109866 by 777
Our goal is to divide 99109866 by 777.

Step 1:
777 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 777

Advancing to step 2:
99 divided by 777 is 0 with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Fetch the next digit (1) from the dividend, attach it to 99 and continue: 991 / 777

Going ahead to step 3:
991 divided by 777 is 1 with a remainder of 214.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 777 from 991 to get 214.
Take the next digit (0) from the dividend and append it to 214, then repeat: 2140 / 777

Step 4:
777 goes into 2140 2 times with a remainder of 586.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1554 from 2140 to get 586.
Grab the next digit (9) from the dividend, add it to 586, then carry on: 5869 / 777

Moving on to step 5:
777 can be fit into 5869 7 times, resulting in a remainder of 430.
The next digit of our result is 7. 
Result so far: 127.0
Subtracting 5439 from 5869 leaves us with 430.
Bring next digit (8) of the dividend behind the 430 and repeat the process: 4308 / 777

Step 6:
The number 777 fits into 4308 5 times, leaving a remainder of 423.
Use 5 as the next digit of our solution. 
Result so far: 1275.0
Subtract 3885 from 4308 to get 423.
Append the next digit (6) from the dividend to 423 and continue with: 4236 / 777

Moving on to step 7:
4236 divided by 777 is 5 with a remainder of 351.
Use 5 as the next digit of our solution. 
Result so far: 12755.0
Deduct 3885 from 4236 and we're left with 351.
Fetch the next digit (6) from the dividend, attach it to 351 and continue: 3516 / 777

Let's proceed to step 8:
777 can be fit into 3516 4 times, resulting in a remainder of 408.
Record the quotient 4 as the next digit in the result. 
Result so far: 127554.0
If we take 3108 away from 3516, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 9:
The number 777 fits into 4080 5 times, leaving a remainder of 195.
The number 5 becomes the next digit in our result. 
Result so far: 127554.5
If we subtract 3885 from 4080, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 10:
1950 divided by 777 is 2 with a remainder of 396.
The number 2 becomes the next digit in our result. 
Result so far: 127554.52
Subtract 1554 from 1950 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 11:
When dividing 3960 by 777, we get 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 127554.525
If we take 3885 away from 3960, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 12:
When dividing 750 by 777, we get 0 with a remainder of 750.
Write down 0 as next digit of the result. 
Result so far: 127554.525
Subtract 0 from 750 to get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Advancing to step 13:
777 goes into 7500 9 times with a remainder of 507.
Record the quotient 9 as the next digit in the result. 
Result so far: 127554.52509
Deduct 6993 from 7500 and we're left with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Moving on to step 14:
777 goes into 5070 6 times with a remainder of 408.
Write down 6 as next digit of the result. 
Result so far: 127554.525096
Subtract 4662 from 5070 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Going ahead to step 15:
4080 divided by 777 is 5 with a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 127554.5250965
Subtract 3885 from 4080 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 16:
777 goes into 1950 2 times with a remainder of 396.
The number 2 becomes the next digit in our result. 
Result so far: 127554.52509652
Subtracting 1554 from 1950 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

The quotient of the division is 127554.52509652, and the remainder is 3.96e-07.
