438771 divided by 55 
The aim is to understand the frequency of 55 in 438771.

Going ahead to step 1:
If we divide 4 by 55, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 55

On to step 2:
When dividing 43 by 55, we get 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 55

Going ahead to step 3:
55 goes into 438 7 times with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 385 from 438 leaves us with 53.
Fetch the next digit (7) from the dividend, attach it to 53 and continue: 537 / 55

On to step 4:
55 goes into 537 9 times with a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 79.0
If we subtract 495 from 537, we get 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 55

Advancing to step 5:
55 can be fit into 427 7 times, resulting in a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 797.0
Subtracting 385 from 427 leaves us with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 55

Moving on to step 6:
If we divide 421 by 55, we get 7 and a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 7977.0
The remainder is 36 after subtracting 385 from 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 7:
55 can be fit into 360 6 times, resulting in a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 7977.6
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
If we divide 300 by 55, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 7977.65
Deduct 275 from 300 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
55 can be fit into 250 4 times, resulting in a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 7977.654
Deduct 220 from 250 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
The number 55 fits into 300 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 7977.6545
If we take 275 away from 300, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
55 can be fit into 250 4 times, resulting in a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 7977.65454
If we take 220 away from 250, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
55 can be fit into 300 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 7977.654545
If we subtract 275 from 300, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 13:
If we divide 250 by 55, we get 4 and a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 7977.6545454
Subtract 220 from 250 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
If we divide 300 by 55, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 7977.65454545
Subtracting 275 from 300 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 7977.65454545 and a remainder of 2.5e-08.
