26580025 divided by 861 
We want to figure out the number of times 26580025 can be divided by 861.

Moving on to step 1:
861 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 861

Advancing to step 2:
861 can be fit into 26 0 times, resulting in a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 861

On to step 3:
When dividing 265 by 861, we get 0 with a remainder of 265.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 265 and we're left with 265.
Append the next digit (8) from the dividend to 265 and continue with: 2658 / 861

On to step 4:
The number 861 fits into 2658 3 times, leaving a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 2583 from 2658 leaves us with 75.
Include the next digit (0) from the dividend after 75, then repeat: 750 / 861

Going ahead to step 5:
750 divided by 861 is 0 with a remainder of 750.
The next digit of our result is 0. 
Result so far: 30.0
Subtracting 0 from 750 leaves us with 750.
Grab the next digit (0) from the dividend, add it to 750, then carry on: 7500 / 861

Going ahead to step 6:
When dividing 7500 by 861, we get 8 with a remainder of 612.
The next digit of our result is 8. 
Result so far: 308.0
If we subtract 6888 from 7500, we get 612.
Include the next digit (2) from the dividend after 612, then repeat: 6122 / 861

Let's proceed to step 7:
When dividing 6122 by 861, we get 7 with a remainder of 95.
The next digit of our result is 7. 
Result so far: 3087.0
Subtracting 6027 from 6122 leaves us with 95.
Include the next digit (5) from the dividend after 95, then repeat: 955 / 861

Going ahead to step 8:
When dividing 955 by 861, we get 1 with a remainder of 94.
Put 1 as the next digit of the answer. 
Result so far: 30871.0
The remainder is 94 after subtracting 861 from 955.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 9:
If we divide 940 by 861, we get 1 and a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 30871.1
If we subtract 861 from 940, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 10:
861 can be fit into 790 0 times, resulting in a remainder of 790.
Put 0 as the next digit of the answer. 
Result so far: 30871.1
Deduct 0 from 790 and we're left with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Going ahead to step 11:
If we divide 7900 by 861, we get 9 and a remainder of 151.
Put 9 as the next digit of the answer. 
Result so far: 30871.109
Subtract 7749 from 7900 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Moving on to step 12:
If we divide 1510 by 861, we get 1 and a remainder of 649.
Write down 1 as next digit of the result. 
Result so far: 30871.1091
The remainder is 649 after subtracting 861 from 1510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

On to step 13:
When dividing 6490 by 861, we get 7 with a remainder of 463.
Record the quotient 7 as the next digit in the result. 
Result so far: 30871.10917
Subtracting 6027 from 6490 leaves us with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Moving on to step 14:
861 goes into 4630 5 times with a remainder of 325.
Put 5 as the next digit of the answer. 
Result so far: 30871.109175
The remainder is 325 after subtracting 4305 from 4630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 15:
When dividing 3250 by 861, we get 3 with a remainder of 667.
Write down 3 as next digit of the result. 
Result so far: 30871.1091753
Deduct 2583 from 3250 and we're left with 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

Step 16:
When dividing 6670 by 861, we get 7 with a remainder of 643.
The next digit of our result is 7. 
Result so far: 30871.10917537
If we subtract 6027 from 6670, we get 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

After the division, we end up with 30871.10917537 and a remainder of 6.43e-07.
