61664555 divided by 56 
The aim is to understand the frequency of 56 in 61664555.

Step 1:
56 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 56

Step 2:
56 goes into 61 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 56 away from 61, we end up with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 56

On to step 3:
When dividing 56 by 56, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 56 from 56 leaves us with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 56

Going ahead to step 4:
The number 56 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 110.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 56

Moving on to step 5:
64 divided by 56 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1101.0
Subtracting 56 from 64 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 56

Let's proceed to step 6:
85 divided by 56 is 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 11011.0
If we take 56 away from 85, we end up with 29.
Grab the next digit (5) from the dividend, add it to 29, then carry on: 295 / 56

On to step 7:
295 divided by 56 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 110115.0
If we subtract 280 from 295, we get 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 56

Going ahead to step 8:
When dividing 155 by 56, we get 2 with a remainder of 43.
Record the quotient 2 as the next digit in the result. 
Result so far: 1101152.0
If we subtract 112 from 155, 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.

Going ahead to step 9:
If we divide 430 by 56, we get 7 and a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 1101152.7
Deduct 392 from 430 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
When dividing 380 by 56, we get 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 1101152.76
Subtract 336 from 380 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
56 can be fit into 440 7 times, resulting in a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 1101152.767
Subtracting 392 from 440 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
56 goes into 480 8 times with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 1101152.7678
If we subtract 448 from 480, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
When dividing 320 by 56, we get 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 1101152.76785
If we subtract 280 from 320, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
56 goes into 400 7 times with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 1101152.767857
The remainder is 8 after subtracting 392 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 15:
When dividing 80 by 56, we get 1 with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1101152.7678571
Subtract 56 from 80 to get 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 16:
When dividing 240 by 56, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 1101152.76785714
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 1101152.76785714 with a remainder of 1.6e-08.
