91089613 ÷ 443 
We want to figure out the number of times 91089613 can be divided by 443.

Going ahead to step 1:
9 divided by 443 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 443

Let's proceed to step 2:
When dividing 91 by 443, we get 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Grab the next digit (0) from the dividend, add it to 91, then carry on: 910 / 443

On to step 3:
910 divided by 443 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 886 away from 910, we end up with 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 443

Step 4:
248 divided by 443 is 0 with a remainder of 248.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 248, we end up with 248.
Take the next digit (9) from the dividend and append it to 248, then repeat: 2489 / 443

On to step 5:
The number 443 fits into 2489 5 times, leaving a remainder of 274.
Write down 5 as next digit of the result. 
Result so far: 205.0
If we take 2215 away from 2489, we end up with 274.
Append the next digit (6) from the dividend to 274 and continue with: 2746 / 443

On to step 6:
443 can be fit into 2746 6 times, resulting in a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 2056.0
If we subtract 2658 from 2746, we get 88.
Fetch the next digit (1) from the dividend, attach it to 88 and continue: 881 / 443

Let's proceed to step 7:
443 goes into 881 1 times with a remainder of 438.
The number 1 becomes the next digit in our result. 
Result so far: 20561.0
The remainder is 438 after subtracting 443 from 881.
Bring next digit (3) of the dividend behind the 438 and repeat the process: 4383 / 443

Moving on to step 8:
If we divide 4383 by 443, we get 9 and a remainder of 396.
Write down 9 as next digit of the result. 
Result so far: 205619.0
Subtract 3987 from 4383 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 9:
When dividing 3960 by 443, we get 8 with a remainder of 416.
Use 8 as the next digit of our solution. 
Result so far: 205619.8
If we take 3544 away from 3960, we end up with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 10:
443 can be fit into 4160 9 times, resulting in a remainder of 173.
Record the quotient 9 as the next digit in the result. 
Result so far: 205619.89
Deduct 3987 from 4160 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Step 11:
When dividing 1730 by 443, we get 3 with a remainder of 401.
Write down 3 as next digit of the result. 
Result so far: 205619.893
Deduct 1329 from 1730 and we're left with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

On to step 12:
443 can be fit into 4010 9 times, resulting in a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 205619.8939
If we subtract 3987 from 4010, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 13:
When dividing 230 by 443, we get 0 with a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 205619.8939
If we subtract 0 from 230, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 14:
If we divide 2300 by 443, we get 5 and a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 205619.893905
Subtract 2215 from 2300 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 15:
If we divide 850 by 443, we get 1 and a remainder of 407.
Record the quotient 1 as the next digit in the result. 
Result so far: 205619.8939051
If we subtract 443 from 850, we get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Going ahead to step 16:
4070 divided by 443 is 9 with a remainder of 83.
The next digit of our result is 9. 
Result so far: 205619.89390519
The remainder is 83 after subtracting 3987 from 4070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The final result is 205619.89390519 with a remainder of 8.3e-08.
