Let's divide 863643 by 55
The aim is to understand the frequency of 55 in 863643.

Moving on to step 1:
If we divide 8 by 55, we get 0 and 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.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 55

Moving on to step 2:
55 goes into 86 1 times with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 55 from 86 leaves us with 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 55

Let's proceed to step 3:
When dividing 313 by 55, we get 5 with a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 275 from 313 leaves us with 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 55

Let's proceed to step 4:
55 can be fit into 386 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
Subtract 385 from 386 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 55

Moving on to step 5:
The number 55 fits into 14 0 times, leaving a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 1570.0
Subtracting 0 from 14 leaves us with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 55

Going ahead to step 6:
The number 55 fits into 143 2 times, leaving a remainder of 33.
Put 2 as the next digit of the answer. 
Result so far: 15702.0
Subtract 110 from 143 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
55 goes into 330 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 15702.6
If we subtract 330 from 330, 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.

Advancing to step 8:
55 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 15702.6
Subtracting 0 from 0 leaves us 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: 15702.6
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.

The quotient of the division is 15702.6, and the remainder is 0.0.
