We look at the division of 78225870 by 977 
We want to figure out the number of times 78225870 can be divided by 977.

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
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 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
Subtract 0 from 78 to get 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 977

Let's proceed to step 3:
If we divide 782 by 977, we get 0 and a remainder of 782.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 782 to get 782.
Grab the next digit (2) from the dividend, add it to 782, then carry on: 7822 / 977

Let's proceed to step 4:
When dividing 7822 by 977, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 7816 from 7822 leaves us with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 977

Step 5:
977 can be fit into 65 0 times, resulting in a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
If we take 0 away from 65, we end up with 65.
Fetch the next digit (8) from the dividend, attach it to 65 and continue: 658 / 977

On to step 6:
If we divide 658 by 977, we get 0 and a remainder of 658.
Write down 0 as next digit of the result. 
Result so far: 800.0
If we take 0 away from 658, we end up with 658.
Fetch the next digit (7) from the dividend, attach it to 658 and continue: 6587 / 977

On to step 7:
If we divide 6587 by 977, we get 6 and a remainder of 725.
Use 6 as the next digit of our solution. 
Result so far: 8006.0
The remainder is 725 after subtracting 5862 from 6587.
Include the next digit (0) from the dividend after 725, then repeat: 7250 / 977

Moving on to step 8:
977 goes into 7250 7 times with a remainder of 411.
The next digit of our result is 7. 
Result so far: 80067.0
Subtract 6839 from 7250 to get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Let's proceed to step 9:
The number 977 fits into 4110 4 times, leaving a remainder of 202.
Write down 4 as next digit of the result. 
Result so far: 80067.4
Subtract 3908 from 4110 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 10:
2020 divided by 977 is 2 with a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 80067.42
Subtracting 1954 from 2020 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 11:
The number 977 fits into 660 0 times, leaving a remainder of 660.
The number 0 becomes the next digit in our result. 
Result so far: 80067.42
If we take 0 away from 660, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 12:
977 goes into 6600 6 times with a remainder of 738.
Use 6 as the next digit of our solution. 
Result so far: 80067.4206
Subtracting 5862 from 6600 leaves us with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Step 13:
977 can be fit into 7380 7 times, resulting in a remainder of 541.
Put 7 as the next digit of the answer. 
Result so far: 80067.42067
The remainder is 541 after subtracting 6839 from 7380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Advancing to step 14:
When dividing 5410 by 977, we get 5 with a remainder of 525.
Put 5 as the next digit of the answer. 
Result so far: 80067.420675
If we take 4885 away from 5410, we end up with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Step 15:
977 can be fit into 5250 5 times, resulting in a remainder of 365.
The number 5 becomes the next digit in our result. 
Result so far: 80067.4206755
If we subtract 4885 from 5250, we get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

The final outcome is 80067.4206755, with a leftover of 3.65e-06.
