We look at the division of 72221976 by 861 
We want to divide 72221976 by 861.

Going ahead to step 1:
861 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 861

Advancing to step 2:
72 divided by 861 is 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Bring next digit (2) of the dividend behind the 72 and repeat the process: 722 / 861

On to step 3:
722 divided by 861 is 0 with a remainder of 722.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 722, we end up with 722.
Take the next digit (2) from the dividend and append it to 722, then repeat: 7222 / 861

Moving on to step 4:
7222 divided by 861 is 8 with a remainder of 334.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 6888 from 7222, we get 334.
Fetch the next digit (1) from the dividend, attach it to 334 and continue: 3341 / 861

On to step 5:
The number 861 fits into 3341 3 times, leaving a remainder of 758.
Write down 3 as next digit of the result. 
Result so far: 83.0
Subtract 2583 from 3341 to get 758.
Include the next digit (9) from the dividend after 758, then repeat: 7589 / 861

Moving on to step 6:
861 goes into 7589 8 times with a remainder of 701.
The next digit of our result is 8. 
Result so far: 838.0
Subtracting 6888 from 7589 leaves us with 701.
Take the next digit (7) from the dividend and append it to 701, then repeat: 7017 / 861

Going ahead to step 7:
The number 861 fits into 7017 8 times, leaving a remainder of 129.
The number 8 becomes the next digit in our result. 
Result so far: 8388.0
If we subtract 6888 from 7017, we get 129.
Fetch the next digit (6) from the dividend, attach it to 129 and continue: 1296 / 861

On to step 8:
1296 divided by 861 is 1 with a remainder of 435.
Put 1 as the next digit of the answer. 
Result so far: 83881.0
If we take 861 away from 1296, we end up with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Step 9:
If we divide 4350 by 861, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 83881.5
The remainder is 45 after subtracting 4305 from 4350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 10:
450 divided by 861 is 0 with a remainder of 450.
The next digit of our result is 0. 
Result so far: 83881.5
The remainder is 450 after subtracting 0 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 11:
The number 861 fits into 4500 5 times, leaving a remainder of 195.
The next digit of our result is 5. 
Result so far: 83881.505
Subtract 4305 from 4500 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 12:
1950 divided by 861 is 2 with a remainder of 228.
Use 2 as the next digit of our solution. 
Result so far: 83881.5052
If we take 1722 away from 1950, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 13:
2280 divided by 861 is 2 with a remainder of 558.
Record the quotient 2 as the next digit in the result. 
Result so far: 83881.50522
Subtracting 1722 from 2280 leaves us with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

After the division, we end up with 83881.50522 and a remainder of 0.000558.
