858506 divided by 55 
The aim is to understand the frequency of 55 in 858506.

Going ahead to step 1:
55 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 55

Step 2:
85 divided by 55 is 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 55 from 85 leaves us with 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 55

Step 3:
308 divided by 55 is 5 with a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 275 away from 308, we end up with 33.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 55

Moving on to step 4:
55 can be fit into 335 6 times, resulting in a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
The remainder is 5 after subtracting 330 from 335.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 55

Advancing to step 5:
The number 55 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 1560.0
Subtract 0 from 50 to get 50.
Grab the next digit (6) from the dividend, add it to 50, then carry on: 506 / 55

Step 6:
55 can be fit into 506 9 times, resulting in a remainder of 11.
The next digit of our result is 9. 
Result so far: 15609.0
Deduct 495 from 506 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
The number 55 fits into 110 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 15609.2
If we take 110 away from 110, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 55 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15609.2
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 55 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15609.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 15609.2 with a remaining 0.0.
