661898 divided by 36 
Let's see how many times 36 fits into 661898.

Moving on to step 1:
The number 36 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 36

On to step 2:
The number 36 fits into 66 1 times, leaving a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 36 from 66, we get 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 36

On to step 3:
The number 36 fits into 301 8 times, leaving a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 288 from 301 to get 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 36

Advancing to step 4:
If we divide 138 by 36, we get 3 and a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 183.0
Deduct 108 from 138 and we're left with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 36

Let's proceed to step 5:
When dividing 309 by 36, we get 8 with a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 1838.0
The remainder is 21 after subtracting 288 from 309.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 36

Moving on to step 6:
When dividing 218 by 36, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 18386.0
If we subtract 216 from 218, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
20 divided by 36 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 18386.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
The number 36 fits into 200 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 18386.05
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
When dividing 200 by 36, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 18386.055
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 18386.055 and a remainder of 0.002.
