We're dividing 51545502 by 564 
The aim is to understand the frequency of 564 in 51545502.

Going ahead to step 1:
The number 564 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 564

Let's proceed to step 2:
564 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 564

Going ahead to step 3:
The number 564 fits into 515 0 times, leaving a remainder of 515.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 515 after subtracting 0 from 515.
Append the next digit (4) from the dividend to 515 and continue with: 5154 / 564

On to step 4:
The number 564 fits into 5154 9 times, leaving a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 5076 from 5154, we get 78.
Bring next digit (5) of the dividend behind the 78 and repeat the process: 785 / 564

On to step 5:
564 goes into 785 1 times with a remainder of 221.
Put 1 as the next digit of the answer. 
Result so far: 91.0
If we take 564 away from 785, we end up with 221.
Take the next digit (5) from the dividend and append it to 221, then repeat: 2215 / 564

On to step 6:
2215 divided by 564 is 3 with a remainder of 523.
Write down 3 as next digit of the result. 
Result so far: 913.0
Deduct 1692 from 2215 and we're left with 523.
Bring next digit (0) of the dividend behind the 523 and repeat the process: 5230 / 564

Going ahead to step 7:
The number 564 fits into 5230 9 times, leaving a remainder of 154.
Put 9 as the next digit of the answer. 
Result so far: 9139.0
If we subtract 5076 from 5230, we get 154.
Grab the next digit (2) from the dividend, add it to 154, then carry on: 1542 / 564

Step 8:
564 goes into 1542 2 times with a remainder of 414.
Write down 2 as next digit of the result. 
Result so far: 91392.0
Deduct 1128 from 1542 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 9:
When dividing 4140 by 564, we get 7 with a remainder of 192.
Put 7 as the next digit of the answer. 
Result so far: 91392.7
The remainder is 192 after subtracting 3948 from 4140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 10:
564 goes into 1920 3 times with a remainder of 228.
Put 3 as the next digit of the answer. 
Result so far: 91392.73
If we take 1692 away from 1920, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 11:
The number 564 fits into 2280 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 91392.734
Deduct 2256 from 2280 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
When dividing 240 by 564, we get 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 91392.734
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 13:
564 can be fit into 2400 4 times, resulting in a remainder of 144.
The number 4 becomes the next digit in our result. 
Result so far: 91392.73404
If we subtract 2256 from 2400, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 14:
When dividing 1440 by 564, we get 2 with a remainder of 312.
The number 2 becomes the next digit in our result. 
Result so far: 91392.734042
If we take 1128 away from 1440, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 15:
564 can be fit into 3120 5 times, resulting in a remainder of 300.
Write down 5 as next digit of the result. 
Result so far: 91392.7340425
Deduct 2820 from 3120 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 16:
When dividing 3000 by 564, we get 5 with a remainder of 180.
The number 5 becomes the next digit in our result. 
Result so far: 91392.73404255
If we take 2820 away from 3000, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

After the division, we end up with 91392.73404255 and a remainder of 1.8e-07.
