Let's divide 645737 by 56
The aim is to understand the frequency of 56 in 645737.

Going ahead to step 1:
The number 56 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 56

On to step 2:
56 goes into 64 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 56 from 64, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 56

Step 3:
56 goes into 85 1 times with a remainder of 29.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 56 from 85 to get 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 56

Going ahead to step 4:
297 divided by 56 is 5 with a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 115.0
Deduct 280 from 297 and we're left with 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 56

Step 5:
56 goes into 173 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 1153.0
The remainder is 5 after subtracting 168 from 173.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 56

Going ahead to step 6:
57 divided by 56 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 11531.0
Subtract 56 from 57 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
If we divide 10 by 56, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 11531.0
Subtracting 0 from 10 leaves us 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.

Step 8:
The number 56 fits into 100 1 times, leaving a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 11531.01
Deduct 56 from 100 and we're left with 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 9:
The number 56 fits into 440 7 times, leaving a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 11531.017
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.

On to step 10:
When dividing 480 by 56, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 11531.0178
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.

On to step 11:
320 divided by 56 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 11531.01785
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.

Moving on to step 12:
56 goes into 400 7 times with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 11531.017857
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 13:
56 can be fit into 80 1 times, resulting in a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 11531.0178571
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.

Going ahead to step 14:
56 goes into 240 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 11531.01785714
Deduct 224 from 240 and we're left 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 11531.01785714 with a remainder of 1.6e-08.
