We're dividing 91216507 by 181 
We want to figure out the number of times 91216507 can be divided by 181.

Going ahead to step 1:
9 divided by 181 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 181

Going ahead to step 2:
The number 181 fits into 91 0 times, leaving a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Take the next digit (2) from the dividend and append it to 91, then repeat: 912 / 181

Step 3:
The number 181 fits into 912 5 times, leaving a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 7 after subtracting 905 from 912.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 181

Let's proceed to step 4:
71 divided by 181 is 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we take 0 away from 71, we end up with 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 181

Advancing to step 5:
181 goes into 716 3 times with a remainder of 173.
The next digit of our result is 3. 
Result so far: 503.0
Deduct 543 from 716 and we're left with 173.
Take the next digit (5) from the dividend and append it to 173, then repeat: 1735 / 181

Let's proceed to step 6:
The number 181 fits into 1735 9 times, leaving a remainder of 106.
The number 9 becomes the next digit in our result. 
Result so far: 5039.0
The remainder is 106 after subtracting 1629 from 1735.
Grab the next digit (0) from the dividend, add it to 106, then carry on: 1060 / 181

Advancing to step 7:
181 goes into 1060 5 times with a remainder of 155.
Record the quotient 5 as the next digit in the result. 
Result so far: 50395.0
If we subtract 905 from 1060, we get 155.
Fetch the next digit (7) from the dividend, attach it to 155 and continue: 1557 / 181

Going ahead to step 8:
181 goes into 1557 8 times with a remainder of 109.
Use 8 as the next digit of our solution. 
Result so far: 503958.0
Deduct 1448 from 1557 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 9:
1090 divided by 181 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 503958.6
The remainder is 4 after subtracting 1086 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
181 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 503958.6
Subtracting 0 from 40 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.

Step 11:
If we divide 400 by 181, we get 2 and a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 503958.602
If we take 362 away from 400, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
380 divided by 181 is 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 503958.6022
Subtract 362 from 380 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 503958.6022, and the remainder is 0.00018.
