Let's divide 80866751 by 261
We want to figure out the number of times 80866751 can be divided by 261.

Moving on to step 1:
8 divided by 261 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 261

Moving on to step 2:
When dividing 80 by 261, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Fetch the next digit (8) from the dividend, attach it to 80 and continue: 808 / 261

Going ahead to step 3:
261 can be fit into 808 3 times, resulting in a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 783 from 808, we get 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 261

Going ahead to step 4:
If we divide 256 by 261, we get 0 and a remainder of 256.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtract 0 from 256 to get 256.
Grab the next digit (6) from the dividend, add it to 256, then carry on: 2566 / 261

Moving on to step 5:
261 goes into 2566 9 times with a remainder of 217.
Put 9 as the next digit of the answer. 
Result so far: 309.0
If we take 2349 away from 2566, we end up with 217.
Take the next digit (7) from the dividend and append it to 217, then repeat: 2177 / 261

Going ahead to step 6:
261 goes into 2177 8 times with a remainder of 89.
The number 8 becomes the next digit in our result. 
Result so far: 3098.0
Subtracting 2088 from 2177 leaves us with 89.
Bring next digit (5) of the dividend behind the 89 and repeat the process: 895 / 261

Moving on to step 7:
261 goes into 895 3 times with a remainder of 112.
Put 3 as the next digit of the answer. 
Result so far: 30983.0
Subtracting 783 from 895 leaves us with 112.
Bring next digit (1) of the dividend behind the 112 and repeat the process: 1121 / 261

Going ahead to step 8:
When dividing 1121 by 261, we get 4 with a remainder of 77.
The number 4 becomes the next digit in our result. 
Result so far: 309834.0
If we take 1044 away from 1121, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 9:
770 divided by 261 is 2 with a remainder of 248.
Put 2 as the next digit of the answer. 
Result so far: 309834.2
Deduct 522 from 770 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 10:
261 can be fit into 2480 9 times, resulting in a remainder of 131.
Use 9 as the next digit of our solution. 
Result so far: 309834.29
If we take 2349 away from 2480, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Moving on to step 11:
If we divide 1310 by 261, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 309834.295
If we subtract 1305 from 1310, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
261 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 309834.295
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
If we divide 500 by 261, we get 1 and a remainder of 239.
Write down 1 as next digit of the result. 
Result so far: 309834.29501
The remainder is 239 after subtracting 261 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Let's proceed to step 14:
When dividing 2390 by 261, we get 9 with a remainder of 41.
The next digit of our result is 9. 
Result so far: 309834.295019
The remainder is 41 after subtracting 2349 from 2390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 15:
When dividing 410 by 261, we get 1 with a remainder of 149.
Record the quotient 1 as the next digit in the result. 
Result so far: 309834.2950191
If we subtract 261 from 410, we get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 16:
If we divide 1490 by 261, we get 5 and a remainder of 185.
The next digit of our result is 5. 
Result so far: 309834.29501915
If we take 1305 away from 1490, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

In conclusion, the division gives 309834.29501915 with a balance of 1.85e-07.
