We're dividing 151572 by 56 
The aim is to understand the frequency of 56 in 151572.

Going ahead to step 1:
1 divided by 56 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 56

On to step 2:
If we divide 15 by 56, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 56

Step 3:
When dividing 151 by 56, we get 2 with a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 112 from 151 and we're left with 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 56

Going ahead to step 4:
56 can be fit into 395 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtract 392 from 395 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 56

On to step 5:
37 divided by 56 is 0 with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 270.0
Deduct 0 from 37 and we're left with 37.
Append the next digit (2) from the dividend to 37 and continue with: 372 / 56

Moving on to step 6:
The number 56 fits into 372 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 2706.0
Subtract 336 from 372 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
When dividing 360 by 56, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 2706.6
Deduct 336 from 360 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.

Advancing to step 8:
If we divide 240 by 56, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 2706.64
If we take 224 away from 240, we end up 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.

Step 9:
56 can be fit into 160 2 times, resulting in a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 2706.642
The remainder is 48 after subtracting 112 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
If we divide 480 by 56, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 2706.6428
Deduct 448 from 480 and we're left 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.

Advancing to step 11:
If we divide 320 by 56, we get 5 and a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 2706.64285
Deduct 280 from 320 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
56 can be fit into 400 7 times, resulting in a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 2706.642857
If we subtract 392 from 400, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
If we divide 80 by 56, we get 1 and a remainder of 24.
The next digit of our result is 1. 
Result so far: 2706.6428571
Subtracting 56 from 80 leaves us 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.

Advancing to step 14:
If we divide 240 by 56, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 2706.64285714
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 2706.64285714 with a remainder of 1.6e-08.
