We're dividing 85508794 by 569 
The aim is to understand the frequency of 569 in 85508794.

Step 1:
569 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 569

Moving on to step 2:
When dividing 85 by 569, we get 0 with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Bring next digit (5) of the dividend behind the 85 and repeat the process: 855 / 569

On to step 3:
855 divided by 569 is 1 with a remainder of 286.
The next digit of our result is 1. 
Result so far: 1.0
If we take 569 away from 855, we end up with 286.
Append the next digit (0) from the dividend to 286 and continue with: 2860 / 569

On to step 4:
When dividing 2860 by 569, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 2845 from 2860 and we're left with 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 569

Advancing to step 5:
If we divide 158 by 569, we get 0 and a remainder of 158.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
Subtracting 0 from 158 leaves us with 158.
Append the next digit (7) from the dividend to 158 and continue with: 1587 / 569

On to step 6:
569 can be fit into 1587 2 times, resulting in a remainder of 449.
Write down 2 as next digit of the result. 
Result so far: 1502.0
Subtracting 1138 from 1587 leaves us with 449.
Fetch the next digit (9) from the dividend, attach it to 449 and continue: 4499 / 569

Moving on to step 7:
569 goes into 4499 7 times with a remainder of 516.
The next digit of our result is 7. 
Result so far: 15027.0
If we take 3983 away from 4499, we end up with 516.
Bring next digit (4) of the dividend behind the 516 and repeat the process: 5164 / 569

On to step 8:
If we divide 5164 by 569, we get 9 and a remainder of 43.
The next digit of our result is 9. 
Result so far: 150279.0
If we subtract 5121 from 5164, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 9:
430 divided by 569 is 0 with a remainder of 430.
Write down 0 as next digit of the result. 
Result so far: 150279.0
Subtracting 0 from 430 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 10:
If we divide 4300 by 569, we get 7 and a remainder of 317.
The number 7 becomes the next digit in our result. 
Result so far: 150279.07
If we subtract 3983 from 4300, we get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Moving on to step 11:
When dividing 3170 by 569, we get 5 with a remainder of 325.
The next digit of our result is 5. 
Result so far: 150279.075
If we subtract 2845 from 3170, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 12:
The number 569 fits into 3250 5 times, leaving a remainder of 405.
The next digit of our result is 5. 
Result so far: 150279.0755
Subtracting 2845 from 3250 leaves us with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

The final outcome is 150279.0755, with a leftover of 0.00405.
