We look at the division of 437837 by 55 
The aim is to understand the frequency of 55 in 437837.

On to step 1:
4 divided by 55 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 55

Moving on to step 2:
The number 55 fits into 43 0 times, leaving a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 55

Moving on to step 3:
If we divide 437 by 55, we get 7 and a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 385 from 437 leaves us with 52.
Grab the next digit (8) from the dividend, add it to 52, then carry on: 528 / 55

Step 4:
55 can be fit into 528 9 times, resulting in a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 79.0
The remainder is 33 after subtracting 495 from 528.
Fetch the next digit (3) from the dividend, attach it to 33 and continue: 333 / 55

On to step 5:
55 can be fit into 333 6 times, resulting in a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 796.0
Subtract 330 from 333 to get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 55

On to step 6:
When dividing 37 by 55, we get 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 7960.0
Subtract 0 from 37 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
If we divide 370 by 55, we get 6 and a remainder of 40.
The next digit of our result is 6. 
Result so far: 7960.6
If we subtract 330 from 370, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
If we divide 400 by 55, we get 7 and a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 7960.67
Deduct 385 from 400 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
55 goes into 150 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 7960.672
If we take 110 away from 150, 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.

Moving on to step 10:
If we divide 400 by 55, we get 7 and a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 7960.6727
If we subtract 385 from 400, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
When dividing 150 by 55, we get 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 7960.67272
Subtracting 110 from 150 leaves us 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.

Advancing to step 12:
55 goes into 400 7 times with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 7960.672727
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
55 can be fit into 150 2 times, resulting in a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 7960.6727272
If we take 110 away from 150, 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.

Let's proceed to step 14:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 7960.67272727
If we take 385 away from 400, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 7960.67272727, and the remainder is 1.5e-08.
