215291 ÷ 56 
The aim is to understand the frequency of 56 in 215291.

On to step 1:
When dividing 2 by 56, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 56

Advancing to step 2:
If we divide 21 by 56, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 56

Advancing to step 3:
The number 56 fits into 215 3 times, leaving a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 168 from 215 and we're left with 47.
Append the next digit (2) from the dividend to 47 and continue with: 472 / 56

Let's proceed to step 4:
The number 56 fits into 472 8 times, leaving a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtracting 448 from 472 leaves us with 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 56

Moving on to step 5:
56 goes into 249 4 times with a remainder of 25.
The next digit of our result is 4. 
Result so far: 384.0
Deduct 224 from 249 and we're left with 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 56

On to step 6:
When dividing 251 by 56, we get 4 with a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 3844.0
Subtract 224 from 251 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
56 can be fit into 270 4 times, resulting in a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 3844.4
Subtracting 224 from 270 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
460 divided by 56 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 3844.48
If we take 448 away from 460, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
120 divided by 56 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 3844.482
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
56 goes into 80 1 times with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 3844.4821
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.

Let's proceed to step 11:
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: 3844.48214
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
56 can be fit into 160 2 times, resulting in a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 3844.482142
Subtract 112 from 160 to 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.

Let's proceed to step 13:
56 goes into 480 8 times with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 3844.4821428
Subtract 448 from 480 to 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.

Step 14:
320 divided by 56 is 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 3844.48214285
If we take 280 away from 320, we end up 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.

The final outcome is 3844.48214285, with a leftover of 4e-08.
