57747857 divided by 820 
We want to figure out the number of times 57747857 can be divided by 820.

Step 1:
The number 820 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 820

Step 2:
If we divide 57 by 820, we get 0 and a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Fetch the next digit (7) from the dividend, attach it to 57 and continue: 577 / 820

On to step 3:
577 divided by 820 is 0 with a remainder of 577.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 577 after subtracting 0 from 577.
Bring next digit (4) of the dividend behind the 577 and repeat the process: 5774 / 820

Advancing to step 4:
If we divide 5774 by 820, we get 7 and a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 5740 from 5774, we get 34.
Append the next digit (7) from the dividend to 34 and continue with: 347 / 820

On to step 5:
The number 820 fits into 347 0 times, leaving a remainder of 347.
Put 0 as the next digit of the answer. 
Result so far: 70.0
If we subtract 0 from 347, we get 347.
Take the next digit (8) from the dividend and append it to 347, then repeat: 3478 / 820

Going ahead to step 6:
820 goes into 3478 4 times with a remainder of 198.
The next digit of our result is 4. 
Result so far: 704.0
If we subtract 3280 from 3478, we get 198.
Append the next digit (5) from the dividend to 198 and continue with: 1985 / 820

Moving on to step 7:
1985 divided by 820 is 2 with a remainder of 345.
Put 2 as the next digit of the answer. 
Result so far: 7042.0
The remainder is 345 after subtracting 1640 from 1985.
Fetch the next digit (7) from the dividend, attach it to 345 and continue: 3457 / 820

On to step 8:
When dividing 3457 by 820, we get 4 with a remainder of 177.
Put 4 as the next digit of the answer. 
Result so far: 70424.0
If we take 3280 away from 3457, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Advancing to step 9:
The number 820 fits into 1770 2 times, leaving a remainder of 130.
The number 2 becomes the next digit in our result. 
Result so far: 70424.2
If we subtract 1640 from 1770, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 10:
1300 divided by 820 is 1 with a remainder of 480.
The next digit of our result is 1. 
Result so far: 70424.21
Subtract 820 from 1300 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 11:
If we divide 4800 by 820, we get 5 and a remainder of 700.
Write down 5 as next digit of the result. 
Result so far: 70424.215
If we subtract 4100 from 4800, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 12:
When dividing 7000 by 820, we get 8 with a remainder of 440.
The next digit of our result is 8. 
Result so far: 70424.2158
Subtract 6560 from 7000 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 13:
When dividing 4400 by 820, we get 5 with a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 70424.21585
If we take 4100 away from 4400, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 14:
When dividing 3000 by 820, we get 3 with a remainder of 540.
Use 3 as the next digit of our solution. 
Result so far: 70424.215853
If we subtract 2460 from 3000, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 15:
The number 820 fits into 5400 6 times, leaving a remainder of 480.
The number 6 becomes the next digit in our result. 
Result so far: 70424.2158536
Subtract 4920 from 5400 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 16:
If we divide 4800 by 820, we get 5 and a remainder of 700.
The next digit of our result is 5. 
Result so far: 70424.21585365
If we subtract 4100 from 4800, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Our division results in 70424.21585365 with a remaining 7e-07.
