Let's divide 91121284 by 405
Our goal is to divide 91121284 by 405.

Advancing to step 1:
The number 405 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 405

Step 2:
405 can be fit into 91 0 times, resulting in a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Append the next digit (1) from the dividend to 91 and continue with: 911 / 405

Step 3:
The number 405 fits into 911 2 times, leaving a remainder of 101.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 101 after subtracting 810 from 911.
Bring next digit (2) of the dividend behind the 101 and repeat the process: 1012 / 405

Step 4:
When dividing 1012 by 405, we get 2 with a remainder of 202.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtracting 810 from 1012 leaves us with 202.
Take the next digit (1) from the dividend and append it to 202, then repeat: 2021 / 405

Step 5:
405 goes into 2021 4 times with a remainder of 401.
Write down 4 as next digit of the result. 
Result so far: 224.0
Subtract 1620 from 2021 to get 401.
Append the next digit (2) from the dividend to 401 and continue with: 4012 / 405

Going ahead to step 6:
When dividing 4012 by 405, we get 9 with a remainder of 367.
Use 9 as the next digit of our solution. 
Result so far: 2249.0
If we subtract 3645 from 4012, we get 367.
Take the next digit (8) from the dividend and append it to 367, then repeat: 3678 / 405

Moving on to step 7:
When dividing 3678 by 405, we get 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 22499.0
If we subtract 3645 from 3678, we get 33.
Take the next digit (4) from the dividend and append it to 33, then repeat: 334 / 405

Going ahead to step 8:
The number 405 fits into 334 0 times, leaving a remainder of 334.
The number 0 becomes the next digit in our result. 
Result so far: 224990.0
Subtracting 0 from 334 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Advancing to step 9:
3340 divided by 405 is 8 with a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 224990.8
Subtracting 3240 from 3340 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
When dividing 1000 by 405, we get 2 with a remainder of 190.
The number 2 becomes the next digit in our result. 
Result so far: 224990.82
Subtract 810 from 1000 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 11:
1900 divided by 405 is 4 with a remainder of 280.
Use 4 as the next digit of our solution. 
Result so far: 224990.824
If we subtract 1620 from 1900, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 12:
When dividing 2800 by 405, we get 6 with a remainder of 370.
The number 6 becomes the next digit in our result. 
Result so far: 224990.8246
If we subtract 2430 from 2800, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 13:
If we divide 3700 by 405, we get 9 and a remainder of 55.
Use 9 as the next digit of our solution. 
Result so far: 224990.82469
Deduct 3645 from 3700 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 14:
When dividing 550 by 405, we get 1 with a remainder of 145.
Use 1 as the next digit of our solution. 
Result so far: 224990.824691
The remainder is 145 after subtracting 405 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 15:
1450 divided by 405 is 3 with a remainder of 235.
Put 3 as the next digit of the answer. 
Result so far: 224990.8246913
The remainder is 235 after subtracting 1215 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 16:
If we divide 2350 by 405, we get 5 and a remainder of 325.
Put 5 as the next digit of the answer. 
Result so far: 224990.82469135
If we take 2025 away from 2350, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

In conclusion, the division gives 224990.82469135 with a balance of 3.25e-07.
