91509977 divided by 204 
We want to figure out the number of times 91509977 can be divided by 204.

Advancing to step 1:
204 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 204

Moving on to step 2:
204 goes into 91 0 times with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Bring next digit (5) of the dividend behind the 91 and repeat the process: 915 / 204

Moving on to step 3:
The number 204 fits into 915 4 times, leaving a remainder of 99.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 816 away from 915, we end up with 99.
Take the next digit (0) from the dividend and append it to 99, then repeat: 990 / 204

Advancing to step 4:
204 can be fit into 990 4 times, resulting in a remainder of 174.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we subtract 816 from 990, we get 174.
Include the next digit (9) from the dividend after 174, then repeat: 1749 / 204

On to step 5:
When dividing 1749 by 204, we get 8 with a remainder of 117.
Record the quotient 8 as the next digit in the result. 
Result so far: 448.0
Deduct 1632 from 1749 and we're left with 117.
Append the next digit (9) from the dividend to 117 and continue with: 1179 / 204

Let's proceed to step 6:
The number 204 fits into 1179 5 times, leaving a remainder of 159.
The number 5 becomes the next digit in our result. 
Result so far: 4485.0
Subtracting 1020 from 1179 leaves us with 159.
Include the next digit (7) from the dividend after 159, then repeat: 1597 / 204

Advancing to step 7:
204 can be fit into 1597 7 times, resulting in a remainder of 169.
The next digit of our result is 7. 
Result so far: 44857.0
Subtract 1428 from 1597 to get 169.
Grab the next digit (7) from the dividend, add it to 169, then carry on: 1697 / 204

Advancing to step 8:
The number 204 fits into 1697 8 times, leaving a remainder of 65.
Put 8 as the next digit of the answer. 
Result so far: 448578.0
Subtracting 1632 from 1697 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
650 divided by 204 is 3 with a remainder of 38.
The next digit of our result is 3. 
Result so far: 448578.3
If we take 612 away from 650, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
204 goes into 380 1 times with a remainder of 176.
Record the quotient 1 as the next digit in the result. 
Result so far: 448578.31
If we take 204 away from 380, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 11:
204 goes into 1760 8 times with a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 448578.318
Subtract 1632 from 1760 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 12:
The number 204 fits into 1280 6 times, leaving a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 448578.3186
If we subtract 1224 from 1280, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 13:
The number 204 fits into 560 2 times, leaving a remainder of 152.
Use 2 as the next digit of our solution. 
Result so far: 448578.31862
Subtracting 408 from 560 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 14:
204 can be fit into 1520 7 times, resulting in a remainder of 92.
Put 7 as the next digit of the answer. 
Result so far: 448578.318627
Deduct 1428 from 1520 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 15:
204 can be fit into 920 4 times, resulting in a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 448578.3186274
If we take 816 away from 920, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 16:
1040 divided by 204 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 448578.31862745
If we take 1020 away from 1040, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 448578.31862745 with a remainder of 2e-08.
