91177518 ÷ 803 
We want to figure out the number of times 91177518 can be divided by 803.

Going ahead to step 1:
803 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 803

Advancing to step 2:
When dividing 91 by 803, we get 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Grab the next digit (1) from the dividend, add it to 91, then carry on: 911 / 803

Let's proceed to step 3:
803 can be fit into 911 1 times, resulting in a remainder of 108.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 803 from 911 and we're left with 108.
Include the next digit (7) from the dividend after 108, then repeat: 1087 / 803

Let's proceed to step 4:
803 can be fit into 1087 1 times, resulting in a remainder of 284.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 803 from 1087, we get 284.
Grab the next digit (7) from the dividend, add it to 284, then carry on: 2847 / 803

On to step 5:
The number 803 fits into 2847 3 times, leaving a remainder of 438.
Use 3 as the next digit of our solution. 
Result so far: 113.0
Subtracting 2409 from 2847 leaves us with 438.
Include the next digit (5) from the dividend after 438, then repeat: 4385 / 803

Step 6:
803 can be fit into 4385 5 times, resulting in a remainder of 370.
Record the quotient 5 as the next digit in the result. 
Result so far: 1135.0
Subtract 4015 from 4385 to get 370.
Bring next digit (1) of the dividend behind the 370 and repeat the process: 3701 / 803

Moving on to step 7:
803 goes into 3701 4 times with a remainder of 489.
Put 4 as the next digit of the answer. 
Result so far: 11354.0
If we subtract 3212 from 3701, we get 489.
Grab the next digit (8) from the dividend, add it to 489, then carry on: 4898 / 803

Advancing to step 8:
If we divide 4898 by 803, we get 6 and a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 113546.0
If we take 4818 away from 4898, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 9:
The number 803 fits into 800 0 times, leaving a remainder of 800.
Write down 0 as next digit of the result. 
Result so far: 113546.0
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Step 10:
When dividing 8000 by 803, we get 9 with a remainder of 773.
Use 9 as the next digit of our solution. 
Result so far: 113546.09
If we subtract 7227 from 8000, we get 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7730, and continue the process.

Moving on to step 11:
When dividing 7730 by 803, we get 9 with a remainder of 503.
Write down 9 as next digit of the result. 
Result so far: 113546.099
If we take 7227 away from 7730, we end up with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

The final result is 113546.099 with a remainder of 0.0503.
