78790025 ÷ 977 
Let's see how many times 977 fits into 78790025.

Let's proceed to step 1:
When dividing 7 by 977, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 977

On to step 2:
78 divided by 977 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Append the next digit (7) from the dividend to 78 and continue with: 787 / 977

On to step 3:
If we divide 787 by 977, we get 0 and a remainder of 787.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 787 to get 787.
Include the next digit (9) from the dividend after 787, then repeat: 7879 / 977

On to step 4:
977 goes into 7879 8 times with a remainder of 63.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 7816 from 7879 to get 63.
Bring next digit (0) of the dividend behind the 63 and repeat the process: 630 / 977

Moving on to step 5:
977 goes into 630 0 times with a remainder of 630.
Write down 0 as next digit of the result. 
Result so far: 80.0
If we subtract 0 from 630, we get 630.
Take the next digit (0) from the dividend and append it to 630, then repeat: 6300 / 977

Step 6:
If we divide 6300 by 977, we get 6 and a remainder of 438.
Use 6 as the next digit of our solution. 
Result so far: 806.0
Deduct 5862 from 6300 and we're left with 438.
Bring next digit (2) of the dividend behind the 438 and repeat the process: 4382 / 977

Let's proceed to step 7:
977 goes into 4382 4 times with a remainder of 474.
Put 4 as the next digit of the answer. 
Result so far: 8064.0
Deduct 3908 from 4382 and we're left with 474.
Fetch the next digit (5) from the dividend, attach it to 474 and continue: 4745 / 977

Advancing to step 8:
977 can be fit into 4745 4 times, resulting in a remainder of 837.
Record the quotient 4 as the next digit in the result. 
Result so far: 80644.0
Subtract 3908 from 4745 to get 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:
The number 977 fits into 8370 8 times, leaving a remainder of 554.
Use 8 as the next digit of our solution. 
Result so far: 80644.8
Subtract 7816 from 8370 to get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Going ahead to step 10:
5540 divided by 977 is 5 with a remainder of 655.
Write down 5 as next digit of the result. 
Result so far: 80644.85
The remainder is 655 after subtracting 4885 from 5540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Advancing to step 11:
When dividing 6550 by 977, we get 6 with a remainder of 688.
Put 6 as the next digit of the answer. 
Result so far: 80644.856
Subtracting 5862 from 6550 leaves us with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Step 12:
6880 divided by 977 is 7 with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 80644.8567
Subtract 6839 from 6880 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 13:
977 can be fit into 410 0 times, resulting in a remainder of 410.
The next digit of our result is 0. 
Result so far: 80644.8567
Deduct 0 from 410 and we're left 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 14:
If we divide 4100 by 977, we get 4 and a remainder of 192.
The next digit of our result is 4. 
Result so far: 80644.856704
The remainder is 192 after subtracting 3908 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 15:
977 can be fit into 1920 1 times, resulting in a remainder of 943.
Use 1 as the next digit of our solution. 
Result so far: 80644.8567041
Subtract 977 from 1920 to get 943.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9430, and continue the process.

Moving on to step 16:
When dividing 9430 by 977, we get 9 with a remainder of 637.
Write down 9 as next digit of the result. 
Result so far: 80644.85670419
If we take 8793 away from 9430, we end up with 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

The final outcome is 80644.85670419, with a leftover of 6.37e-07.
