Let's divide 17996161 by 210
We're looking to find how many times 210 goes into 17996161.

Going ahead to step 1:
210 goes into 1 0 times 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.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 210

Moving on to step 2:
210 can be fit into 17 0 times, resulting in a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 210

Step 3:
210 can be fit into 179 0 times, resulting in a remainder of 179.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 179 leaves us with 179.
Append the next digit (9) from the dividend to 179 and continue with: 1799 / 210

Advancing to step 4:
210 can be fit into 1799 8 times, resulting in a remainder of 119.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 119 after subtracting 1680 from 1799.
Grab the next digit (6) from the dividend, add it to 119, then carry on: 1196 / 210

Going ahead to step 5:
210 goes into 1196 5 times with a remainder of 146.
Write down 5 as next digit of the result. 
Result so far: 85.0
Subtracting 1050 from 1196 leaves us with 146.
Take the next digit (1) from the dividend and append it to 146, then repeat: 1461 / 210

Going ahead to step 6:
210 can be fit into 1461 6 times, resulting in a remainder of 201.
Use 6 as the next digit of our solution. 
Result so far: 856.0
Subtract 1260 from 1461 to get 201.
Take the next digit (6) from the dividend and append it to 201, then repeat: 2016 / 210

Moving on to step 7:
2016 divided by 210 is 9 with a remainder of 126.
The number 9 becomes the next digit in our result. 
Result so far: 8569.0
Subtracting 1890 from 2016 leaves us with 126.
Take the next digit (1) from the dividend and append it to 126, then repeat: 1261 / 210

Let's proceed to step 8:
210 can be fit into 1261 6 times, resulting in a remainder of 1.
The next digit of our result is 6. 
Result so far: 85696.0
Subtract 1260 from 1261 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
210 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 85696.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
The number 210 fits into 100 0 times, leaving a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 85696.0
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 85696.0 and a remainder of 0.1.
