864211 ÷ 56 
The aim is to understand the frequency of 56 in 864211.

Step 1:
When dividing 8 by 56, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 56

On to step 2:
If we divide 86 by 56, we get 1 and a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 30 after subtracting 56 from 86.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 56

Advancing to step 3:
304 divided by 56 is 5 with a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 280 from 304 to get 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 56

Advancing to step 4:
If we divide 242 by 56, we get 4 and a remainder of 18.
The next digit of our result is 4. 
Result so far: 154.0
If we take 224 away from 242, we end up with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 56

On to step 5:
56 goes into 181 3 times with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 1543.0
Subtract 168 from 181 to get 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 56

Advancing to step 6:
If we divide 131 by 56, we get 2 and a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 15432.0
If we take 112 away from 131, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
56 goes into 190 3 times with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 15432.3
Subtract 168 from 190 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
The number 56 fits into 220 3 times, leaving a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 15432.33
If we subtract 168 from 220, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 15432.33, with a leftover of 0.052.
