Let's divide 74776721 by 830
We want to figure out the number of times 74776721 can be divided by 830.

Moving on to step 1:
When dividing 7 by 830, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 830

Moving on to step 2:
If we divide 74 by 830, we get 0 and a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Include the next digit (7) from the dividend after 74, then repeat: 747 / 830

On to step 3:
830 can be fit into 747 0 times, resulting in a remainder of 747.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 747 after subtracting 0 from 747.
Take the next digit (7) from the dividend and append it to 747, then repeat: 7477 / 830

Advancing to step 4:
If we divide 7477 by 830, we get 9 and a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 7470 from 7477 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 830

Advancing to step 5:
If we divide 76 by 830, we get 0 and a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
Subtract 0 from 76 to get 76.
Fetch the next digit (7) from the dividend, attach it to 76 and continue: 767 / 830

Step 6:
When dividing 767 by 830, we get 0 with a remainder of 767.
Put 0 as the next digit of the answer. 
Result so far: 900.0
The remainder is 767 after subtracting 0 from 767.
Fetch the next digit (2) from the dividend, attach it to 767 and continue: 7672 / 830

On to step 7:
7672 divided by 830 is 9 with a remainder of 202.
Put 9 as the next digit of the answer. 
Result so far: 9009.0
Subtract 7470 from 7672 to get 202.
Include the next digit (1) from the dividend after 202, then repeat: 2021 / 830

Advancing to step 8:
2021 divided by 830 is 2 with a remainder of 361.
Put 2 as the next digit of the answer. 
Result so far: 90092.0
Subtract 1660 from 2021 to get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Going ahead to step 9:
If we divide 3610 by 830, we get 4 and a remainder of 290.
The next digit of our result is 4. 
Result so far: 90092.4
If we subtract 3320 from 3610, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 10:
830 goes into 2900 3 times with a remainder of 410.
Use 3 as the next digit of our solution. 
Result so far: 90092.43
Subtracting 2490 from 2900 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 11:
830 goes into 4100 4 times with a remainder of 780.
The number 4 becomes the next digit in our result. 
Result so far: 90092.434
Subtracting 3320 from 4100 leaves us with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Step 12:
When dividing 7800 by 830, we get 9 with a remainder of 330.
Put 9 as the next digit of the answer. 
Result so far: 90092.4349
If we take 7470 away from 7800, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 13:
When dividing 3300 by 830, we get 3 with a remainder of 810.
Write down 3 as next digit of the result. 
Result so far: 90092.43493
Subtracting 2490 from 3300 leaves us with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Going ahead to step 14:
The number 830 fits into 8100 9 times, leaving a remainder of 630.
Record the quotient 9 as the next digit in the result. 
Result so far: 90092.434939
Subtract 7470 from 8100 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 15:
If we divide 6300 by 830, we get 7 and a remainder of 490.
Record the quotient 7 as the next digit in the result. 
Result so far: 90092.4349397
The remainder is 490 after subtracting 5810 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 16:
If we divide 4900 by 830, we get 5 and a remainder of 750.
Record the quotient 5 as the next digit in the result. 
Result so far: 90092.43493975
If we subtract 4150 from 4900, we 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.

The final result is 90092.43493975 with a remainder of 7.5e-07.
