We're dividing 91289169 by 284 
We want to figure out the number of times 91289169 can be divided by 284.

Step 1:
284 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 284

Advancing to step 2:
When dividing 91 by 284, we get 0 with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Append the next digit (2) from the dividend to 91 and continue with: 912 / 284

Moving on to step 3:
284 can be fit into 912 3 times, resulting in a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 852 from 912 to get 60.
Grab the next digit (8) from the dividend, add it to 60, then carry on: 608 / 284

On to step 4:
284 goes into 608 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we take 568 away from 608, we end up with 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 284

On to step 5:
409 divided by 284 is 1 with a remainder of 125.
Put 1 as the next digit of the answer. 
Result so far: 321.0
Deduct 284 from 409 and we're left with 125.
Grab the next digit (1) from the dividend, add it to 125, then carry on: 1251 / 284

On to step 6:
284 goes into 1251 4 times with a remainder of 115.
Write down 4 as next digit of the result. 
Result so far: 3214.0
Subtracting 1136 from 1251 leaves us with 115.
Append the next digit (6) from the dividend to 115 and continue with: 1156 / 284

Advancing to step 7:
If we divide 1156 by 284, we get 4 and a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 32144.0
Subtract 1136 from 1156 to get 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 284

Moving on to step 8:
The number 284 fits into 209 0 times, leaving a remainder of 209.
Use 0 as the next digit of our solution. 
Result so far: 321440.0
The remainder is 209 after subtracting 0 from 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 9:
284 can be fit into 2090 7 times, resulting in a remainder of 102.
Put 7 as the next digit of the answer. 
Result so far: 321440.7
Subtract 1988 from 2090 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 10:
The number 284 fits into 1020 3 times, leaving a remainder of 168.
The number 3 becomes the next digit in our result. 
Result so far: 321440.73
Subtract 852 from 1020 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 11:
1680 divided by 284 is 5 with a remainder of 260.
The next digit of our result is 5. 
Result so far: 321440.735
If we take 1420 away from 1680, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 12:
2600 divided by 284 is 9 with a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 321440.7359
The remainder is 44 after subtracting 2556 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
284 goes into 440 1 times with a remainder of 156.
Put 1 as the next digit of the answer. 
Result so far: 321440.73591
The remainder is 156 after subtracting 284 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 14:
If we divide 1560 by 284, we get 5 and a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 321440.735915
The remainder is 140 after subtracting 1420 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 15:
If we divide 1400 by 284, we get 4 and a remainder of 264.
Record the quotient 4 as the next digit in the result. 
Result so far: 321440.7359154
If we subtract 1136 from 1400, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 16:
If we divide 2640 by 284, we get 9 and a remainder of 84.
The number 9 becomes the next digit in our result. 
Result so far: 321440.73591549
If we subtract 2556 from 2640, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final outcome is 321440.73591549, with a leftover of 8.4e-08.
