81530406 ÷ 55 
We want to figure out the number of times 81530406 can be divided by 55.

Advancing to step 1:
55 can be fit into 8 0 times, resulting in 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.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 55

Going ahead to step 2:
81 divided by 55 is 1 with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 55 from 81 and we're left with 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 55

Going ahead to step 3:
When dividing 265 by 55, we get 4 with a remainder of 45.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 220 from 265 leaves us with 45.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 55

Advancing to step 4:
When dividing 453 by 55, we get 8 with a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
Subtracting 440 from 453 leaves us with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 55

On to step 5:
55 goes into 130 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 1482.0
Deduct 110 from 130 and we're left with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 55

Step 6:
55 goes into 204 3 times with a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 14823.0
Subtracting 165 from 204 leaves us with 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 55

Step 7:
When dividing 390 by 55, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 148237.0
If we take 385 away from 390, we end up with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 55

Advancing to step 8:
When dividing 56 by 55, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1482371.0
If we take 55 away from 56, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
When dividing 10 by 55, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1482371.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
If we divide 100 by 55, we get 1 and a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 1482371.01
If we take 55 away from 100, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 11:
55 goes into 450 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 1482371.018
Subtract 440 from 450 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
If we divide 100 by 55, we get 1 and a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 1482371.0181
If we take 55 away from 100, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
If we divide 450 by 55, we get 8 and a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 1482371.01818
The remainder is 10 after subtracting 440 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
If we divide 100 by 55, we get 1 and a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 1482371.018181
Deduct 55 from 100 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 15:
When dividing 450 by 55, we get 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 1482371.0181818
Subtract 440 from 450 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 16:
The number 55 fits into 100 1 times, leaving a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 1482371.01818181
Subtracting 55 from 100 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Our division results in 1482371.01818181 with a remaining 4.5e-08.
