68989392 divided by 564 
The aim is to understand the frequency of 564 in 68989392.

Step 1:
6 divided by 564 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 564

Let's proceed to step 2:
If we divide 68 by 564, we get 0 and a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Append the next digit (9) from the dividend to 68 and continue with: 689 / 564

Let's proceed to step 3:
The number 564 fits into 689 1 times, leaving a remainder of 125.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 564 from 689 to get 125.
Fetch the next digit (8) from the dividend, attach it to 125 and continue: 1258 / 564

Let's proceed to step 4:
564 can be fit into 1258 2 times, resulting in a remainder of 130.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 1128 away from 1258, we end up with 130.
Take the next digit (9) from the dividend and append it to 130, then repeat: 1309 / 564

Moving on to step 5:
564 goes into 1309 2 times with a remainder of 181.
Use 2 as the next digit of our solution. 
Result so far: 122.0
If we take 1128 away from 1309, we end up with 181.
Bring next digit (3) of the dividend behind the 181 and repeat the process: 1813 / 564

On to step 6:
When dividing 1813 by 564, we get 3 with a remainder of 121.
Use 3 as the next digit of our solution. 
Result so far: 1223.0
Subtract 1692 from 1813 to get 121.
Fetch the next digit (9) from the dividend, attach it to 121 and continue: 1219 / 564

Step 7:
If we divide 1219 by 564, we get 2 and a remainder of 91.
Use 2 as the next digit of our solution. 
Result so far: 12232.0
If we subtract 1128 from 1219, we get 91.
Include the next digit (2) from the dividend after 91, then repeat: 912 / 564

Moving on to step 8:
When dividing 912 by 564, we get 1 with a remainder of 348.
Record the quotient 1 as the next digit in the result. 
Result so far: 122321.0
If we subtract 564 from 912, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 9:
564 can be fit into 3480 6 times, resulting in a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 122321.6
The remainder is 96 after subtracting 3384 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 10:
564 goes into 960 1 times with a remainder of 396.
Record the quotient 1 as the next digit in the result. 
Result so far: 122321.61
If we subtract 564 from 960, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 11:
If we divide 3960 by 564, we get 7 and a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 122321.617
Deduct 3948 from 3960 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
564 goes into 120 0 times with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 122321.617
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 13:
1200 divided by 564 is 2 with a remainder of 72.
The next digit of our result is 2. 
Result so far: 122321.61702
If we take 1128 away from 1200, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 14:
When dividing 720 by 564, we get 1 with a remainder of 156.
Write down 1 as next digit of the result. 
Result so far: 122321.617021
The remainder is 156 after subtracting 564 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 15:
The number 564 fits into 1560 2 times, leaving a remainder of 432.
The number 2 becomes the next digit in our result. 
Result so far: 122321.6170212
Subtracting 1128 from 1560 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 16:
564 can be fit into 4320 7 times, resulting in a remainder of 372.
Use 7 as the next digit of our solution. 
Result so far: 122321.61702127
Subtracting 3948 from 4320 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

The final outcome is 122321.61702127, with a leftover of 3.72e-07.
