61586097 divided by 528 
The aim is to understand the frequency of 528 in 61586097.

Advancing to step 1:
6 divided by 528 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 528

Let's proceed to step 2:
The number 528 fits into 61 0 times, leaving a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Grab the next digit (5) from the dividend, add it to 61, then carry on: 615 / 528

Advancing to step 3:
615 divided by 528 is 1 with a remainder of 87.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 87 after subtracting 528 from 615.
Bring next digit (8) of the dividend behind the 87 and repeat the process: 878 / 528

Advancing to step 4:
If we divide 878 by 528, we get 1 and a remainder of 350.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 528 from 878 leaves us with 350.
Grab the next digit (6) from the dividend, add it to 350, then carry on: 3506 / 528

Moving on to step 5:
528 goes into 3506 6 times with a remainder of 338.
Write down 6 as next digit of the result. 
Result so far: 116.0
If we take 3168 away from 3506, we end up with 338.
Grab the next digit (0) from the dividend, add it to 338, then carry on: 3380 / 528

On to step 6:
The number 528 fits into 3380 6 times, leaving a remainder of 212.
Put 6 as the next digit of the answer. 
Result so far: 1166.0
The remainder is 212 after subtracting 3168 from 3380.
Append the next digit (9) from the dividend to 212 and continue with: 2129 / 528

Step 7:
2129 divided by 528 is 4 with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 11664.0
Subtracting 2112 from 2129 leaves us with 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 528

On to step 8:
If we divide 177 by 528, we get 0 and a remainder of 177.
The next digit of our result is 0. 
Result so far: 116640.0
If we subtract 0 from 177, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Moving on to step 9:
The number 528 fits into 1770 3 times, leaving a remainder of 186.
The number 3 becomes the next digit in our result. 
Result so far: 116640.3
The remainder is 186 after subtracting 1584 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 10:
1860 divided by 528 is 3 with a remainder of 276.
Use 3 as the next digit of our solution. 
Result so far: 116640.33
Subtract 1584 from 1860 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

After the division, we end up with 116640.33 and a remainder of 0.276.
