We look at the division of 18010646 by 261 
We want to divide 18010646 by 261.

Let's proceed to step 1:
The number 261 fits into 1 0 times, leaving 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.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 261

Step 2:
261 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 261

Let's proceed to step 3:
261 goes into 180 0 times with a remainder of 180.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 180 and we're left with 180.
Append the next digit (1) from the dividend to 180 and continue with: 1801 / 261

Let's proceed to step 4:
1801 divided by 261 is 6 with a remainder of 235.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 1566 from 1801 to get 235.
Grab the next digit (0) from the dividend, add it to 235, then carry on: 2350 / 261

Let's proceed to step 5:
The number 261 fits into 2350 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
If we subtract 2349 from 2350, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 261

Let's proceed to step 6:
The number 261 fits into 16 0 times, leaving a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 690.0
The remainder is 16 after subtracting 0 from 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 261

On to step 7:
164 divided by 261 is 0 with a remainder of 164.
The number 0 becomes the next digit in our result. 
Result so far: 6900.0
Subtracting 0 from 164 leaves us with 164.
Append the next digit (6) from the dividend to 164 and continue with: 1646 / 261

On to step 8:
When dividing 1646 by 261, we get 6 with a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 69006.0
The remainder is 80 after subtracting 1566 from 1646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 9:
If we divide 800 by 261, we get 3 and a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 69006.3
Subtract 783 from 800 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
170 divided by 261 is 0 with a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 69006.3
The remainder is 170 after subtracting 0 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 11:
When dividing 1700 by 261, we get 6 with a remainder of 134.
Put 6 as the next digit of the answer. 
Result so far: 69006.306
The remainder is 134 after subtracting 1566 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 12:
1340 divided by 261 is 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 69006.3065
Subtracting 1305 from 1340 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 13:
350 divided by 261 is 1 with a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 69006.30651
Subtracting 261 from 350 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 14:
261 can be fit into 890 3 times, resulting in a remainder of 107.
The next digit of our result is 3. 
Result so far: 69006.306513
Subtracting 783 from 890 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 15:
261 can be fit into 1070 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 69006.3065134
The remainder is 26 after subtracting 1044 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 16:
261 goes into 260 0 times with a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 69006.3065134
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Our division results in 69006.3065134 with a remaining 2.6e-07.
