We look at the division of 22815716 by 861 
We want to figure out the number of times 22815716 can be divided by 861.

Advancing to step 1:
The number 861 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 861

Moving on to step 2:
The number 861 fits into 22 0 times, leaving a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 861

On to step 3:
The number 861 fits into 228 0 times, leaving a remainder of 228.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 228, we end up with 228.
Append the next digit (1) from the dividend to 228 and continue with: 2281 / 861

Step 4:
The number 861 fits into 2281 2 times, leaving a remainder of 559.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 1722 away from 2281, we end up with 559.
Include the next digit (5) from the dividend after 559, then repeat: 5595 / 861

Let's proceed to step 5:
861 can be fit into 5595 6 times, resulting in a remainder of 429.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 429 after subtracting 5166 from 5595.
Take the next digit (7) from the dividend and append it to 429, then repeat: 4297 / 861

Step 6:
If we divide 4297 by 861, we get 4 and a remainder of 853.
The next digit of our result is 4. 
Result so far: 264.0
The remainder is 853 after subtracting 3444 from 4297.
Take the next digit (1) from the dividend and append it to 853, then repeat: 8531 / 861

Let's proceed to step 7:
When dividing 8531 by 861, we get 9 with a remainder of 782.
Use 9 as the next digit of our solution. 
Result so far: 2649.0
The remainder is 782 after subtracting 7749 from 8531.
Fetch the next digit (6) from the dividend, attach it to 782 and continue: 7826 / 861

Moving on to step 8:
7826 divided by 861 is 9 with a remainder of 77.
The number 9 becomes the next digit in our result. 
Result so far: 26499.0
Subtract 7749 from 7826 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 9:
861 can be fit into 770 0 times, resulting in a remainder of 770.
Write down 0 as next digit of the result. 
Result so far: 26499.0
If we subtract 0 from 770, we get 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Going ahead to step 10:
861 goes into 7700 8 times with a remainder of 812.
Put 8 as the next digit of the answer. 
Result so far: 26499.08
The remainder is 812 after subtracting 6888 from 7700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

Let's proceed to step 11:
8120 divided by 861 is 9 with a remainder of 371.
Write down 9 as next digit of the result. 
Result so far: 26499.089
If we take 7749 away from 8120, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Moving on to step 12:
The number 861 fits into 3710 4 times, leaving a remainder of 266.
Put 4 as the next digit of the answer. 
Result so far: 26499.0894
If we take 3444 away from 3710, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 13:
861 goes into 2660 3 times with a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 26499.08943
If we subtract 2583 from 2660, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 14:
The number 861 fits into 770 0 times, leaving a remainder of 770.
The number 0 becomes the next digit in our result. 
Result so far: 26499.08943
Deduct 0 from 770 and we're left with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Advancing to step 15:
7700 divided by 861 is 8 with a remainder of 812.
The number 8 becomes the next digit in our result. 
Result so far: 26499.0894308
If we subtract 6888 from 7700, we get 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

Step 16:
861 goes into 8120 9 times with a remainder of 371.
Put 9 as the next digit of the answer. 
Result so far: 26499.08943089
The remainder is 371 after subtracting 7749 from 8120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

The final outcome is 26499.08943089, with a leftover of 3.71e-07.
