We look at the division of 77587670 by 820 
We're looking to find how many times 820 goes into 77587670.

Moving on to step 1:
7 divided by 820 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 820

Let's proceed to step 2:
If we divide 77 by 820, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (5) from the dividend, attach it to 77 and continue: 775 / 820

Advancing to step 3:
When dividing 775 by 820, we get 0 with a remainder of 775.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 775 after subtracting 0 from 775.
Append the next digit (8) from the dividend to 775 and continue with: 7758 / 820

Going ahead to step 4:
If we divide 7758 by 820, we get 9 and a remainder of 378.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 7380 away from 7758, we end up with 378.
Append the next digit (7) from the dividend to 378 and continue with: 3787 / 820

Step 5:
The number 820 fits into 3787 4 times, leaving a remainder of 507.
Use 4 as the next digit of our solution. 
Result so far: 94.0
If we subtract 3280 from 3787, we get 507.
Take the next digit (6) from the dividend and append it to 507, then repeat: 5076 / 820

Step 6:
The number 820 fits into 5076 6 times, leaving a remainder of 156.
Write down 6 as next digit of the result. 
Result so far: 946.0
If we take 4920 away from 5076, we end up with 156.
Append the next digit (7) from the dividend to 156 and continue with: 1567 / 820

Let's proceed to step 7:
The number 820 fits into 1567 1 times, leaving a remainder of 747.
The number 1 becomes the next digit in our result. 
Result so far: 9461.0
Subtract 820 from 1567 to get 747.
Fetch the next digit (0) from the dividend, attach it to 747 and continue: 7470 / 820

Advancing to step 8:
820 goes into 7470 9 times with a remainder of 90.
Use 9 as the next digit of our solution. 
Result so far: 94619.0
If we subtract 7380 from 7470, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 9:
820 goes into 900 1 times with a remainder of 80.
Use 1 as the next digit of our solution. 
Result so far: 94619.1
Deduct 820 from 900 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
When dividing 800 by 820, we get 0 with a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 94619.1
If we take 0 away from 800, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 11:
If we divide 8000 by 820, we get 9 and a remainder of 620.
Use 9 as the next digit of our solution. 
Result so far: 94619.109
If we subtract 7380 from 8000, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 12:
If we divide 6200 by 820, we get 7 and a remainder of 460.
Put 7 as the next digit of the answer. 
Result so far: 94619.1097
If we subtract 5740 from 6200, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 13:
4600 divided by 820 is 5 with a remainder of 500.
Use 5 as the next digit of our solution. 
Result so far: 94619.10975
If we subtract 4100 from 4600, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 14:
If we divide 5000 by 820, we get 6 and a remainder of 80.
The next digit of our result is 6. 
Result so far: 94619.109756
If we subtract 4920 from 5000, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 15:
The number 820 fits into 800 0 times, leaving a remainder of 800.
Put 0 as the next digit of the answer. 
Result so far: 94619.109756
If we take 0 away from 800, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Advancing to step 16:
820 goes into 8000 9 times with a remainder of 620.
Put 9 as the next digit of the answer. 
Result so far: 94619.10975609
If we subtract 7380 from 8000, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Our division results in 94619.10975609 with a remaining 6.2e-07.
