88992918 divided by 821 
The aim is to understand the frequency of 821 in 88992918.

Moving on to step 1:
When dividing 8 by 821, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 821

On to step 2:
The number 821 fits into 88 0 times, leaving a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 88 after subtracting 0 from 88.
Fetch the next digit (9) from the dividend, attach it to 88 and continue: 889 / 821

On to step 3:
889 divided by 821 is 1 with a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 821 away from 889, we end up with 68.
Grab the next digit (9) from the dividend, add it to 68, then carry on: 689 / 821

Let's proceed to step 4:
If we divide 689 by 821, we get 0 and a remainder of 689.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 689 to get 689.
Take the next digit (2) from the dividend and append it to 689, then repeat: 6892 / 821

Let's proceed to step 5:
821 goes into 6892 8 times with a remainder of 324.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
The remainder is 324 after subtracting 6568 from 6892.
Fetch the next digit (9) from the dividend, attach it to 324 and continue: 3249 / 821

Moving on to step 6:
821 goes into 3249 3 times with a remainder of 786.
Put 3 as the next digit of the answer. 
Result so far: 1083.0
Deduct 2463 from 3249 and we're left with 786.
Bring next digit (1) of the dividend behind the 786 and repeat the process: 7861 / 821

Advancing to step 7:
7861 divided by 821 is 9 with a remainder of 472.
Record the quotient 9 as the next digit in the result. 
Result so far: 10839.0
Subtracting 7389 from 7861 leaves us with 472.
Include the next digit (8) from the dividend after 472, then repeat: 4728 / 821

Advancing to step 8:
821 can be fit into 4728 5 times, resulting in a remainder of 623.
Put 5 as the next digit of the answer. 
Result so far: 108395.0
If we subtract 4105 from 4728, we get 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Let's proceed to step 9:
The number 821 fits into 6230 7 times, leaving a remainder of 483.
Record the quotient 7 as the next digit in the result. 
Result so far: 108395.7
The remainder is 483 after subtracting 5747 from 6230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Step 10:
821 goes into 4830 5 times with a remainder of 725.
Use 5 as the next digit of our solution. 
Result so far: 108395.75
Deduct 4105 from 4830 and we're left with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Advancing to step 11:
The number 821 fits into 7250 8 times, leaving a remainder of 682.
Put 8 as the next digit of the answer. 
Result so far: 108395.758
Subtract 6568 from 7250 to get 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

On to step 12:
If we divide 6820 by 821, we get 8 and a remainder of 252.
The next digit of our result is 8. 
Result so far: 108395.7588
Deduct 6568 from 6820 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Our division results in 108395.7588 with a remaining 0.00252.
