638289 ÷ 55 
We want to figure out the number of times 638289 can be divided by 55.

On to step 1:
55 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 55

Moving on to step 2:
63 divided by 55 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 55 from 63 and we're left with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 55

Let's proceed to step 3:
The number 55 fits into 88 1 times, leaving a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 55 from 88 and we're left with 33.
Bring next digit (2) of the dividend behind the 33 and repeat the process: 332 / 55

Going ahead to step 4:
When dividing 332 by 55, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 116.0
The remainder is 2 after subtracting 330 from 332.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 55

Step 5:
55 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 1160.0
The remainder is 28 after subtracting 0 from 28.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 55

On to step 6:
When dividing 289 by 55, we get 5 with a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 11605.0
Subtract 275 from 289 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
55 can be fit into 140 2 times, resulting in a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 11605.2
Subtracting 110 from 140 leaves us 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.

On to step 8:
When dividing 300 by 55, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 11605.25
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.

Going ahead to step 9:
If we divide 250 by 55, we get 4 and a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 11605.254
The remainder is 30 after subtracting 220 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
300 divided by 55 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 11605.2545
Subtract 275 from 300 to 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.

On to step 11:
55 goes into 250 4 times with a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 11605.25454
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.

Advancing to step 12:
If we divide 300 by 55, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 11605.254545
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 13:
When dividing 250 by 55, we get 4 with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 11605.2545454
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.

Step 14:
When dividing 300 by 55, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 11605.25454545
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.

Our division results in 11605.25454545 with a remaining 2.5e-08.
