91521245 ÷ 804 
We're looking to find how many times 804 goes into 91521245.

On to step 1:
When dividing 9 by 804, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 804

Going ahead to step 2:
804 goes into 91 0 times with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Grab the next digit (5) from the dividend, add it to 91, then carry on: 915 / 804

Advancing to step 3:
If we divide 915 by 804, we get 1 and a remainder of 111.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 804 from 915 and we're left with 111.
Include the next digit (2) from the dividend after 111, then repeat: 1112 / 804

Let's proceed to step 4:
1112 divided by 804 is 1 with a remainder of 308.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 804 from 1112 and we're left with 308.
Take the next digit (1) from the dividend and append it to 308, then repeat: 3081 / 804

Let's proceed to step 5:
If we divide 3081 by 804, we get 3 and a remainder of 669.
Write down 3 as next digit of the result. 
Result so far: 113.0
If we subtract 2412 from 3081, we get 669.
Include the next digit (2) from the dividend after 669, then repeat: 6692 / 804

Step 6:
When dividing 6692 by 804, we get 8 with a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 1138.0
Subtract 6432 from 6692 to get 260.
Include the next digit (4) from the dividend after 260, then repeat: 2604 / 804

On to step 7:
2604 divided by 804 is 3 with a remainder of 192.
The number 3 becomes the next digit in our result. 
Result so far: 11383.0
Deduct 2412 from 2604 and we're left with 192.
Fetch the next digit (5) from the dividend, attach it to 192 and continue: 1925 / 804

On to step 8:
The number 804 fits into 1925 2 times, leaving a remainder of 317.
Write down 2 as next digit of the result. 
Result so far: 113832.0
If we take 1608 away from 1925, we end up with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Advancing to step 9:
If we divide 3170 by 804, we get 3 and a remainder of 758.
Record the quotient 3 as the next digit in the result. 
Result so far: 113832.3
If we subtract 2412 from 3170, we get 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

Let's proceed to step 10:
The number 804 fits into 7580 9 times, leaving a remainder of 344.
Write down 9 as next digit of the result. 
Result so far: 113832.39
The remainder is 344 after subtracting 7236 from 7580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 11:
When dividing 3440 by 804, we get 4 with a remainder of 224.
The next digit of our result is 4. 
Result so far: 113832.394
Subtracting 3216 from 3440 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 12:
If we divide 2240 by 804, we get 2 and a remainder of 632.
The next digit of our result is 2. 
Result so far: 113832.3942
Subtract 1608 from 2240 to get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Advancing to step 13:
804 can be fit into 6320 7 times, resulting in a remainder of 692.
The number 7 becomes the next digit in our result. 
Result so far: 113832.39427
Subtracting 5628 from 6320 leaves us with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Moving on to step 14:
When dividing 6920 by 804, we get 8 with a remainder of 488.
Write down 8 as next digit of the result. 
Result so far: 113832.394278
The remainder is 488 after subtracting 6432 from 6920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Step 15:
If we divide 4880 by 804, we get 6 and a remainder of 56.
The next digit of our result is 6. 
Result so far: 113832.3942786
Deduct 4824 from 4880 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 16:
804 can be fit into 560 0 times, resulting in a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 113832.3942786
Deduct 0 from 560 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

In conclusion, the division gives 113832.3942786 with a balance of 5.6e-07.
