56069837 ÷ 99 
The aim is to understand the frequency of 99 in 56069837.

On to step 1:
The number 99 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 99

Advancing to step 2:
If we divide 56 by 99, we get 0 and a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Fetch the next digit (0) from the dividend, attach it to 56 and continue: 560 / 99

Moving on to step 3:
99 goes into 560 5 times with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 495 from 560 leaves us with 65.
Grab the next digit (6) from the dividend, add it to 65, then carry on: 656 / 99

Moving on to step 4:
656 divided by 99 is 6 with a remainder of 62.
The next digit of our result is 6. 
Result so far: 56.0
Deduct 594 from 656 and we're left with 62.
Bring next digit (9) of the dividend behind the 62 and repeat the process: 629 / 99

Moving on to step 5:
629 divided by 99 is 6 with a remainder of 35.
The number 6 becomes the next digit in our result. 
Result so far: 566.0
If we subtract 594 from 629, we get 35.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 99

Going ahead to step 6:
The number 99 fits into 358 3 times, leaving a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 5663.0
Deduct 297 from 358 and we're left with 61.
Take the next digit (3) from the dividend and append it to 61, then repeat: 613 / 99

Going ahead to step 7:
If we divide 613 by 99, we get 6 and a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 56636.0
If we take 594 away from 613, we end up with 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 99

Moving on to step 8:
If we divide 197 by 99, we get 1 and a remainder of 98.
The next digit of our result is 1. 
Result so far: 566361.0
If we subtract 99 from 197, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 9:
99 can be fit into 980 9 times, resulting in a remainder of 89.
The number 9 becomes the next digit in our result. 
Result so far: 566361.9
Subtracting 891 from 980 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 10:
When dividing 890 by 99, we get 8 with a remainder of 98.
Use 8 as the next digit of our solution. 
Result so far: 566361.98
If we take 792 away from 890, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 11:
When dividing 980 by 99, we get 9 with a remainder of 89.
Put 9 as the next digit of the answer. 
Result so far: 566361.989
Subtracting 891 from 980 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 12:
890 divided by 99 is 8 with a remainder of 98.
Put 8 as the next digit of the answer. 
Result so far: 566361.9898
Subtracting 792 from 890 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 13:
980 divided by 99 is 9 with a remainder of 89.
The next digit of our result is 9. 
Result so far: 566361.98989
If we subtract 891 from 980, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 14:
99 goes into 890 8 times with a remainder of 98.
Use 8 as the next digit of our solution. 
Result so far: 566361.989898
Subtracting 792 from 890 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 15:
The number 99 fits into 980 9 times, leaving a remainder of 89.
The number 9 becomes the next digit in our result. 
Result so far: 566361.9898989
The remainder is 89 after subtracting 891 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 16:
When dividing 890 by 99, we get 8 with a remainder of 98.
Write down 8 as next digit of the result. 
Result so far: 566361.98989898
Subtracting 792 from 890 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

The final outcome is 566361.98989898, with a leftover of 9.8e-08.
