Let's divide 77902331 by 974
We want to divide 77902331 by 974.

Step 1:
If we divide 7 by 974, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 974

Moving on to step 2:
If we divide 77 by 974, we get 0 and 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.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 974

Step 3:
The number 974 fits into 779 0 times, leaving a remainder of 779.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 779 leaves us with 779.
Bring next digit (0) of the dividend behind the 779 and repeat the process: 7790 / 974

On to step 4:
974 goes into 7790 7 times with a remainder of 972.
The next digit of our result is 7. 
Result so far: 7.0
If we take 6818 away from 7790, we end up with 972.
Grab the next digit (2) from the dividend, add it to 972, then carry on: 9722 / 974

Moving on to step 5:
The number 974 fits into 9722 9 times, leaving a remainder of 956.
Write down 9 as next digit of the result. 
Result so far: 79.0
Subtract 8766 from 9722 to get 956.
Append the next digit (3) from the dividend to 956 and continue with: 9563 / 974

Step 6:
974 can be fit into 9563 9 times, resulting in a remainder of 797.
Put 9 as the next digit of the answer. 
Result so far: 799.0
Subtract 8766 from 9563 to get 797.
Grab the next digit (3) from the dividend, add it to 797, then carry on: 7973 / 974

Going ahead to step 7:
974 goes into 7973 8 times with a remainder of 181.
Record the quotient 8 as the next digit in the result. 
Result so far: 7998.0
If we subtract 7792 from 7973, we get 181.
Fetch the next digit (1) from the dividend, attach it to 181 and continue: 1811 / 974

On to step 8:
If we divide 1811 by 974, we get 1 and a remainder of 837.
Use 1 as the next digit of our solution. 
Result so far: 79981.0
If we take 974 away from 1811, we end up with 837.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8370, and continue the process.

Going ahead to step 9:
When dividing 8370 by 974, we get 8 with a remainder of 578.
Record the quotient 8 as the next digit in the result. 
Result so far: 79981.8
Subtract 7792 from 8370 to get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Moving on to step 10:
5780 divided by 974 is 5 with a remainder of 910.
The number 5 becomes the next digit in our result. 
Result so far: 79981.85
If we subtract 4870 from 5780, we get 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9100, and continue the process.

Step 11:
If we divide 9100 by 974, we get 9 and a remainder of 334.
Record the quotient 9 as the next digit in the result. 
Result so far: 79981.859
The remainder is 334 after subtracting 8766 from 9100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 12:
974 goes into 3340 3 times with a remainder of 418.
The next digit of our result is 3. 
Result so far: 79981.8593
Subtract 2922 from 3340 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 13:
4180 divided by 974 is 4 with a remainder of 284.
Use 4 as the next digit of our solution. 
Result so far: 79981.85934
Deduct 3896 from 4180 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 14:
When dividing 2840 by 974, we get 2 with a remainder of 892.
Write down 2 as next digit of the result. 
Result so far: 79981.859342
The remainder is 892 after subtracting 1948 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

Moving on to step 15:
When dividing 8920 by 974, we get 9 with a remainder of 154.
Put 9 as the next digit of the answer. 
Result so far: 79981.8593429
If we subtract 8766 from 8920, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 16:
When dividing 1540 by 974, we get 1 with a remainder of 566.
Record the quotient 1 as the next digit in the result. 
Result so far: 79981.85934291
Subtract 974 from 1540 to get 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

The final result is 79981.85934291 with a remainder of 5.66e-07.
