Let's divide 56985885 by 561
The aim is to understand the frequency of 561 in 56985885.

Let's proceed to step 1:
561 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 561

On to step 2:
56 divided by 561 is 0 with a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Append the next digit (9) from the dividend to 56 and continue with: 569 / 561

Advancing to step 3:
561 can be fit into 569 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 561 from 569 and we're left with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 561

Step 4:
The number 561 fits into 88 0 times, leaving a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 88 leaves us with 88.
Grab the next digit (5) from the dividend, add it to 88, then carry on: 885 / 561

Moving on to step 5:
561 can be fit into 885 1 times, resulting in a remainder of 324.
The next digit of our result is 1. 
Result so far: 101.0
If we take 561 away from 885, we end up with 324.
Grab the next digit (8) from the dividend, add it to 324, then carry on: 3248 / 561

Let's proceed to step 6:
561 can be fit into 3248 5 times, resulting in a remainder of 443.
Write down 5 as next digit of the result. 
Result so far: 1015.0
If we subtract 2805 from 3248, we get 443.
Grab the next digit (8) from the dividend, add it to 443, then carry on: 4438 / 561

Let's proceed to step 7:
When dividing 4438 by 561, we get 7 with a remainder of 511.
Record the quotient 7 as the next digit in the result. 
Result so far: 10157.0
Subtracting 3927 from 4438 leaves us with 511.
Append the next digit (5) from the dividend to 511 and continue with: 5115 / 561

Step 8:
When dividing 5115 by 561, we get 9 with a remainder of 66.
The next digit of our result is 9. 
Result so far: 101579.0
If we subtract 5049 from 5115, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 9:
If we divide 660 by 561, we get 1 and a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 101579.1
If we subtract 561 from 660, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 10:
990 divided by 561 is 1 with a remainder of 429.
The number 1 becomes the next digit in our result. 
Result so far: 101579.11
Subtracting 561 from 990 leaves us with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Our division results in 101579.11 with a remaining 0.429.
