99764198 ÷ 77 
Let's see how many times 77 fits into 99764198.

Moving on to step 1:
77 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.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 77

Step 2:
77 can be fit into 99 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 77 from 99 and we're left with 22.
Bring next digit (7) of the dividend behind the 22 and repeat the process: 227 / 77

Step 3:
227 divided by 77 is 2 with a remainder of 73.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 154 from 227 and we're left with 73.
Take the next digit (6) from the dividend and append it to 73, then repeat: 736 / 77

Moving on to step 4:
If we divide 736 by 77, we get 9 and a remainder of 43.
The next digit of our result is 9. 
Result so far: 129.0
Subtract 693 from 736 to get 43.
Include the next digit (4) from the dividend after 43, then repeat: 434 / 77

Moving on to step 5:
If we divide 434 by 77, we get 5 and a remainder of 49.
The next digit of our result is 5. 
Result so far: 1295.0
Deduct 385 from 434 and we're left with 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 77

Let's proceed to step 6:
77 goes into 491 6 times with a remainder of 29.
Record the quotient 6 as the next digit in the result. 
Result so far: 12956.0
Deduct 462 from 491 and we're left with 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 77

Going ahead to step 7:
The number 77 fits into 299 3 times, leaving a remainder of 68.
The next digit of our result is 3. 
Result so far: 129563.0
Deduct 231 from 299 and we're left with 68.
Fetch the next digit (8) from the dividend, attach it to 68 and continue: 688 / 77

Step 8:
77 can be fit into 688 8 times, resulting in a remainder of 72.
The next digit of our result is 8. 
Result so far: 1295638.0
If we take 616 away from 688, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
When dividing 720 by 77, we get 9 with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 1295638.9
Subtracting 693 from 720 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 10:
270 divided by 77 is 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 1295638.93
Subtracting 231 from 270 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
390 divided by 77 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1295638.935
Subtracting 385 from 390 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 12:
The number 77 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 1295638.935
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
When dividing 500 by 77, we get 6 with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 1295638.93506
Deduct 462 from 500 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 14:
77 goes into 380 4 times with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 1295638.935064
If we take 308 away from 380, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 15:
720 divided by 77 is 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 1295638.9350649
If we subtract 693 from 720, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 16:
The number 77 fits into 270 3 times, leaving a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 1295638.93506493
Subtract 231 from 270 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

In conclusion, the division gives 1295638.93506493 with a balance of 3.9e-08.
