352020 ÷ 55 
The aim is to understand the frequency of 55 in 352020.

On to step 1:
If we divide 3 by 55, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 55

On to step 2:
55 goes into 35 0 times with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 55

Advancing to step 3:
If we divide 352 by 55, we get 6 and a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 22 after subtracting 330 from 352.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 55

Moving on to step 4:
55 goes into 220 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtracting 220 from 220 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 55

Going ahead to step 5:
If we divide 2 by 55, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 640.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 55

On to step 6:
If we divide 20 by 55, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 6400.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
The number 55 fits into 200 3 times, leaving a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 6400.3
Subtract 165 from 200 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
55 goes into 350 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 6400.36
Subtract 330 from 350 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
55 can be fit into 200 3 times, resulting in a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 6400.363
If we subtract 165 from 200, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
If we divide 350 by 55, we get 6 and a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 6400.3636
Subtract 330 from 350 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
55 can be fit into 200 3 times, resulting in a remainder of 35.
The next digit of our result is 3. 
Result so far: 6400.36363
Subtracting 165 from 200 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
The number 55 fits into 350 6 times, leaving a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 6400.363636
If we subtract 330 from 350, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
55 goes into 200 3 times with a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 6400.3636363
Subtract 165 from 200 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
55 goes into 350 6 times with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 6400.36363636
If we take 330 away from 350, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 6400.36363636, with a leftover of 2e-08.
