We're dividing 57208774 by 864 
We want to figure out the number of times 57208774 can be divided by 864.

On to step 1:
When dividing 5 by 864, we get 0 with 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.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 864

On to step 2:
If we divide 57 by 864, we get 0 and a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Append the next digit (2) from the dividend to 57 and continue with: 572 / 864

Advancing to step 3:
When dividing 572 by 864, we get 0 with a remainder of 572.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 572 and we're left with 572.
Take the next digit (0) from the dividend and append it to 572, then repeat: 5720 / 864

On to step 4:
864 can be fit into 5720 6 times, resulting in a remainder of 536.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 5184 from 5720 leaves us with 536.
Append the next digit (8) from the dividend to 536 and continue with: 5368 / 864

On to step 5:
If we divide 5368 by 864, we get 6 and a remainder of 184.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Subtracting 5184 from 5368 leaves us with 184.
Take the next digit (7) from the dividend and append it to 184, then repeat: 1847 / 864

On to step 6:
1847 divided by 864 is 2 with a remainder of 119.
Put 2 as the next digit of the answer. 
Result so far: 662.0
The remainder is 119 after subtracting 1728 from 1847.
Grab the next digit (7) from the dividend, add it to 119, then carry on: 1197 / 864

Advancing to step 7:
864 can be fit into 1197 1 times, resulting in a remainder of 333.
Record the quotient 1 as the next digit in the result. 
Result so far: 6621.0
If we take 864 away from 1197, we end up with 333.
Grab the next digit (4) from the dividend, add it to 333, then carry on: 3334 / 864

Step 8:
864 can be fit into 3334 3 times, resulting in a remainder of 742.
Write down 3 as next digit of the result. 
Result so far: 66213.0
Subtract 2592 from 3334 to get 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Going ahead to step 9:
864 goes into 7420 8 times with a remainder of 508.
Use 8 as the next digit of our solution. 
Result so far: 66213.8
Deduct 6912 from 7420 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Moving on to step 10:
864 can be fit into 5080 5 times, resulting in a remainder of 760.
The number 5 becomes the next digit in our result. 
Result so far: 66213.85
Subtract 4320 from 5080 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Advancing to step 11:
864 can be fit into 7600 8 times, resulting in a remainder of 688.
The next digit of our result is 8. 
Result so far: 66213.858
Deduct 6912 from 7600 and we're left 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.

Moving on to step 12:
The number 864 fits into 6880 7 times, leaving a remainder of 832.
The number 7 becomes the next digit in our result. 
Result so far: 66213.8587
Deduct 6048 from 6880 and we're left with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

On to step 13:
8320 divided by 864 is 9 with a remainder of 544.
The next digit of our result is 9. 
Result so far: 66213.85879
Subtracting 7776 from 8320 leaves us with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 14:
If we divide 5440 by 864, we get 6 and a remainder of 256.
The number 6 becomes the next digit in our result. 
Result so far: 66213.858796
If we take 5184 away from 5440, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 15:
When dividing 2560 by 864, we get 2 with a remainder of 832.
Write down 2 as next digit of the result. 
Result so far: 66213.8587962
If we subtract 1728 from 2560, we get 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Step 16:
8320 divided by 864 is 9 with a remainder of 544.
The next digit of our result is 9. 
Result so far: 66213.85879629
If we take 7776 away from 8320, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

The quotient of the division is 66213.85879629, and the remainder is 5.44e-07.
