We're dividing 18640678 by 861 
We're looking to find how many times 861 goes into 18640678.

Going ahead to step 1:
1 divided by 861 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
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

Let's proceed to step 2:
861 goes into 18 0 times with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 861

Advancing to step 3:
186 divided by 861 is 0 with a remainder of 186.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 186 leaves us with 186.
Bring next digit (4) of the dividend behind the 186 and repeat the process: 1864 / 861

Let's proceed to step 4:
When dividing 1864 by 861, we get 2 with a remainder of 142.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1722 away from 1864, we end up with 142.
Grab the next digit (0) from the dividend, add it to 142, then carry on: 1420 / 861

Moving on to step 5:
861 can be fit into 1420 1 times, resulting in a remainder of 559.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 861 from 1420, we get 559.
Grab the next digit (6) from the dividend, add it to 559, then carry on: 5596 / 861

Step 6:
If we divide 5596 by 861, we get 6 and a remainder of 430.
Put 6 as the next digit of the answer. 
Result so far: 216.0
Deduct 5166 from 5596 and we're left with 430.
Include the next digit (7) from the dividend after 430, then repeat: 4307 / 861

Step 7:
4307 divided by 861 is 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 2165.0
Subtracting 4305 from 4307 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 861

Advancing to step 8:
861 goes into 28 0 times with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 21650.0
If we subtract 0 from 28, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
861 goes into 280 0 times with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 21650.0
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 10:
861 can be fit into 2800 3 times, resulting in a remainder of 217.
Use 3 as the next digit of our solution. 
Result so far: 21650.03
The remainder is 217 after subtracting 2583 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 11:
2170 divided by 861 is 2 with a remainder of 448.
The next digit of our result is 2. 
Result so far: 21650.032
Subtract 1722 from 2170 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 12:
If we divide 4480 by 861, we get 5 and a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 21650.0325
Subtract 4305 from 4480 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 13:
If we divide 1750 by 861, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 21650.03252
Deduct 1722 from 1750 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
280 divided by 861 is 0 with a remainder of 280.
The next digit of our result is 0. 
Result so far: 21650.03252
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 15:
861 can be fit into 2800 3 times, resulting in a remainder of 217.
The number 3 becomes the next digit in our result. 
Result so far: 21650.0325203
Subtract 2583 from 2800 to get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 16:
If we divide 2170 by 861, we get 2 and a remainder of 448.
The next digit of our result is 2. 
Result so far: 21650.03252032
If we take 1722 away from 2170, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

The final outcome is 21650.03252032, with a leftover of 4.48e-07.
