Let's divide 64621715 by 888
We want to figure out the number of times 64621715 can be divided by 888.

Going ahead to step 1:
If we divide 6 by 888, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 888

On to step 2:
888 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 888

On to step 3:
646 divided by 888 is 0 with a remainder of 646.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 646 after subtracting 0 from 646.
Bring next digit (2) of the dividend behind the 646 and repeat the process: 6462 / 888

Moving on to step 4:
The number 888 fits into 6462 7 times, leaving a remainder of 246.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 246 after subtracting 6216 from 6462.
Include the next digit (1) from the dividend after 246, then repeat: 2461 / 888

Step 5:
When dividing 2461 by 888, we get 2 with a remainder of 685.
Write down 2 as next digit of the result. 
Result so far: 72.0
Subtracting 1776 from 2461 leaves us with 685.
Take the next digit (7) from the dividend and append it to 685, then repeat: 6857 / 888

Moving on to step 6:
888 goes into 6857 7 times with a remainder of 641.
The next digit of our result is 7. 
Result so far: 727.0
If we subtract 6216 from 6857, we get 641.
Grab the next digit (1) from the dividend, add it to 641, then carry on: 6411 / 888

Advancing to step 7:
If we divide 6411 by 888, we get 7 and a remainder of 195.
Put 7 as the next digit of the answer. 
Result so far: 7277.0
Subtract 6216 from 6411 to get 195.
Append the next digit (5) from the dividend to 195 and continue with: 1955 / 888

Step 8:
1955 divided by 888 is 2 with a remainder of 179.
The number 2 becomes the next digit in our result. 
Result so far: 72772.0
Subtracting 1776 from 1955 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Moving on to step 9:
When dividing 1790 by 888, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 72772.2
Subtracting 1776 from 1790 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
The number 888 fits into 140 0 times, leaving a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 72772.2
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 11:
1400 divided by 888 is 1 with a remainder of 512.
Use 1 as the next digit of our solution. 
Result so far: 72772.201
Subtracting 888 from 1400 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Moving on to step 12:
888 goes into 5120 5 times with a remainder of 680.
Put 5 as the next digit of the answer. 
Result so far: 72772.2015
If we subtract 4440 from 5120, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Moving on to step 13:
888 can be fit into 6800 7 times, resulting in a remainder of 584.
Write down 7 as next digit of the result. 
Result so far: 72772.20157
Subtract 6216 from 6800 to get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Moving on to step 14:
888 goes into 5840 6 times with a remainder of 512.
Put 6 as the next digit of the answer. 
Result so far: 72772.201576
Subtracting 5328 from 5840 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Moving on to step 15:
888 goes into 5120 5 times with a remainder of 680.
The number 5 becomes the next digit in our result. 
Result so far: 72772.2015765
Subtracting 4440 from 5120 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 16:
When dividing 6800 by 888, we get 7 with a remainder of 584.
The next digit of our result is 7. 
Result so far: 72772.20157657
If we take 6216 away from 6800, we end up with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

In conclusion, the division gives 72772.20157657 with a balance of 5.84e-07.
