89081105 ÷ 172 
Our goal is to divide 89081105 by 172.

Let's proceed to step 1:
If we divide 8 by 172, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 172

Advancing to step 2:
The number 172 fits into 89 0 times, leaving a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Fetch the next digit (0) from the dividend, attach it to 89 and continue: 890 / 172

On to step 3:
If we divide 890 by 172, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 860 away from 890, we end up with 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 172

Advancing to step 4:
When dividing 308 by 172, we get 1 with a remainder of 136.
The next digit of our result is 1. 
Result so far: 51.0
The remainder is 136 after subtracting 172 from 308.
Grab the next digit (1) from the dividend, add it to 136, then carry on: 1361 / 172

Step 5:
When dividing 1361 by 172, we get 7 with a remainder of 157.
Record the quotient 7 as the next digit in the result. 
Result so far: 517.0
Subtracting 1204 from 1361 leaves us with 157.
Fetch the next digit (1) from the dividend, attach it to 157 and continue: 1571 / 172

On to step 6:
172 goes into 1571 9 times with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 5179.0
Subtracting 1548 from 1571 leaves us with 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 172

On to step 7:
172 can be fit into 230 1 times, resulting in a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 51791.0
Deduct 172 from 230 and we're left with 58.
Bring next digit (5) of the dividend behind the 58 and repeat the process: 585 / 172

Advancing to step 8:
172 can be fit into 585 3 times, resulting in a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 517913.0
Subtract 516 from 585 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 9:
172 goes into 690 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 517913.4
Subtract 688 from 690 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
The number 172 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 517913.4
Subtracting 0 from 20 leaves us 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.

Going ahead to step 11:
When dividing 200 by 172, we get 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 517913.401
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
If we divide 280 by 172, we get 1 and a remainder of 108.
Use 1 as the next digit of our solution. 
Result so far: 517913.4011
Deduct 172 from 280 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Our division results in 517913.4011 with a remaining 0.00108.
