78471217 ÷ 888 
The aim is to understand the frequency of 888 in 78471217.

Moving on to step 1:
When dividing 7 by 888, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 888

Going ahead to step 2:
If we divide 78 by 888, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Append the next digit (4) from the dividend to 78 and continue with: 784 / 888

Advancing to step 3:
The number 888 fits into 784 0 times, leaving a remainder of 784.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 784, we get 784.
Bring next digit (7) of the dividend behind the 784 and repeat the process: 7847 / 888

Advancing to step 4:
The number 888 fits into 7847 8 times, leaving a remainder of 743.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 743 after subtracting 7104 from 7847.
Include the next digit (1) from the dividend after 743, then repeat: 7431 / 888

On to step 5:
888 can be fit into 7431 8 times, resulting in a remainder of 327.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Deduct 7104 from 7431 and we're left with 327.
Bring next digit (2) of the dividend behind the 327 and repeat the process: 3272 / 888

On to step 6:
If we divide 3272 by 888, we get 3 and a remainder of 608.
Write down 3 as next digit of the result. 
Result so far: 883.0
The remainder is 608 after subtracting 2664 from 3272.
Bring next digit (1) of the dividend behind the 608 and repeat the process: 6081 / 888

Step 7:
The number 888 fits into 6081 6 times, leaving a remainder of 753.
Write down 6 as next digit of the result. 
Result so far: 8836.0
Deduct 5328 from 6081 and we're left with 753.
Append the next digit (7) from the dividend to 753 and continue with: 7537 / 888

Step 8:
If we divide 7537 by 888, we get 8 and a remainder of 433.
The next digit of our result is 8. 
Result so far: 88368.0
Subtracting 7104 from 7537 leaves us with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Let's proceed to step 9:
4330 divided by 888 is 4 with a remainder of 778.
Write down 4 as next digit of the result. 
Result so far: 88368.4
Subtracting 3552 from 4330 leaves us with 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Let's proceed to step 10:
If we divide 7780 by 888, we get 8 and a remainder of 676.
The next digit of our result is 8. 
Result so far: 88368.48
Deduct 7104 from 7780 and we're left with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Advancing to step 11:
888 goes into 6760 7 times with a remainder of 544.
The next digit of our result is 7. 
Result so far: 88368.487
The remainder is 544 after subtracting 6216 from 6760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 12:
888 goes into 5440 6 times with a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 88368.4876
If we subtract 5328 from 5440, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 13:
The number 888 fits into 1120 1 times, leaving a remainder of 232.
The number 1 becomes the next digit in our result. 
Result so far: 88368.48761
If we take 888 away from 1120, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 14:
888 goes into 2320 2 times with a remainder of 544.
Write down 2 as next digit of the result. 
Result so far: 88368.487612
If we take 1776 away from 2320, 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.

Let's proceed to step 15:
5440 divided by 888 is 6 with a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 88368.4876126
Subtract 5328 from 5440 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 16:
If we divide 1120 by 888, we get 1 and a remainder of 232.
The next digit of our result is 1. 
Result so far: 88368.48761261
If we take 888 away from 1120, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Our division results in 88368.48761261 with a remaining 2.32e-07.
