66719801 divided by 56 
The aim is to understand the frequency of 56 in 66719801.

Going ahead to step 1:
If we divide 6 by 56, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 56

Step 2:
56 can be fit into 66 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 56 from 66 leaves us with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 56

Moving on to step 3:
The number 56 fits into 107 1 times, leaving a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 56 from 107 to get 51.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 56

Step 4:
If we divide 511 by 56, we get 9 and a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
The remainder is 7 after subtracting 504 from 511.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 56

Moving on to step 5:
56 goes into 79 1 times with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1191.0
If we subtract 56 from 79, we get 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 56

Moving on to step 6:
56 can be fit into 238 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 11914.0
Subtracting 224 from 238 leaves us with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 56

On to step 7:
If we divide 140 by 56, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 119142.0
If we take 112 away from 140, we end up with 28.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 56

Going ahead to step 8:
If we divide 281 by 56, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 1191425.0
If we take 280 away from 281, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
If we divide 10 by 56, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1191425.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
The number 56 fits into 100 1 times, leaving a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 1191425.01
Subtract 56 from 100 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.

Advancing to step 11:
56 goes into 440 7 times with a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 1191425.017
If we subtract 392 from 440, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
56 goes into 480 8 times with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 1191425.0178
Subtracting 448 from 480 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
When dividing 320 by 56, we get 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 1191425.01785
The remainder is 40 after subtracting 280 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
400 divided by 56 is 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 1191425.017857
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:
56 goes into 80 1 times with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1191425.0178571
If we subtract 56 from 80, we 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.
The next digit of our result is 4. 
Result so far: 1191425.01785714
Subtracting 224 from 240 leaves us with 16.
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 1191425.01785714 with a remainder of 1.6e-08.
