18073112 divided by 861 
We want to figure out the number of times 18073112 can be divided by 861.

Let's proceed to step 1:
1 divided by 861 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 861

Going ahead to step 2:
If we divide 18 by 861, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 861

Moving on to step 3:
180 divided by 861 is 0 with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 180, we end up with 180.
Grab the next digit (7) from the dividend, add it to 180, then carry on: 1807 / 861

Going ahead to step 4:
The number 861 fits into 1807 2 times, leaving a remainder of 85.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 85 after subtracting 1722 from 1807.
Take the next digit (3) from the dividend and append it to 85, then repeat: 853 / 861

Advancing to step 5:
853 divided by 861 is 0 with a remainder of 853.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 853 and we're left with 853.
Grab the next digit (1) from the dividend, add it to 853, then carry on: 8531 / 861

Step 6:
When dividing 8531 by 861, we get 9 with a remainder of 782.
Record the quotient 9 as the next digit in the result. 
Result so far: 209.0
If we subtract 7749 from 8531, we get 782.
Append the next digit (1) from the dividend to 782 and continue with: 7821 / 861

On to step 7:
When dividing 7821 by 861, we get 9 with a remainder of 72.
The next digit of our result is 9. 
Result so far: 2099.0
The remainder is 72 after subtracting 7749 from 7821.
Bring next digit (2) of the dividend behind the 72 and repeat the process: 722 / 861

Step 8:
When dividing 722 by 861, we get 0 with a remainder of 722.
Write down 0 as next digit of the result. 
Result so far: 20990.0
The remainder is 722 after subtracting 0 from 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Moving on to step 9:
861 goes into 7220 8 times with a remainder of 332.
The next digit of our result is 8. 
Result so far: 20990.8
Subtracting 6888 from 7220 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 10:
The number 861 fits into 3320 3 times, leaving a remainder of 737.
Put 3 as the next digit of the answer. 
Result so far: 20990.83
The remainder is 737 after subtracting 2583 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

Let's proceed to step 11:
When dividing 7370 by 861, we get 8 with a remainder of 482.
The next digit of our result is 8. 
Result so far: 20990.838
Subtract 6888 from 7370 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Let's proceed to step 12:
When dividing 4820 by 861, we get 5 with a remainder of 515.
Put 5 as the next digit of the answer. 
Result so far: 20990.8385
If we subtract 4305 from 4820, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Step 13:
861 can be fit into 5150 5 times, resulting in a remainder of 845.
Record the quotient 5 as the next digit in the result. 
Result so far: 20990.83855
If we subtract 4305 from 5150, we get 845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

The final result is 20990.83855 with a remainder of 0.000845.
