215540 ÷ 99 
We want to divide 215540 by 99.

On to step 1:
99 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 99

Moving on to step 2:
21 divided by 99 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 99

Moving on to step 3:
99 can be fit into 215 2 times, resulting in a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 198 from 215, we get 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 99

Going ahead to step 4:
The number 99 fits into 175 1 times, leaving a remainder of 76.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 76 after subtracting 99 from 175.
Bring next digit (4) of the dividend behind the 76 and repeat the process: 764 / 99

Advancing to step 5:
When dividing 764 by 99, we get 7 with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 217.0
Subtract 693 from 764 to get 71.
Grab the next digit (0) from the dividend, add it to 71, then carry on: 710 / 99

Advancing to step 6:
The number 99 fits into 710 7 times, leaving a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 2177.0
If we take 693 away from 710, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
170 divided by 99 is 1 with a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 2177.1
If we take 99 away from 170, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 8:
99 can be fit into 710 7 times, resulting in a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 2177.17
Subtract 693 from 710 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.

Going ahead to step 9:
99 goes into 170 1 times with a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 2177.171
Subtract 99 from 170 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 10:
99 goes into 710 7 times with a remainder of 17.
The next digit of our result is 7. 
Result so far: 2177.1717
If we take 693 away from 710, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 11:
99 goes into 170 1 times with a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 2177.17171
If we subtract 99 from 170, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 12:
99 goes into 710 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 2177.171717
If we take 693 away from 710, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
The number 99 fits into 170 1 times, leaving a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 2177.1717171
The remainder is 71 after subtracting 99 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 14:
99 goes into 710 7 times with a remainder of 17.
The next digit of our result is 7. 
Result so far: 2177.17171717
Subtract 693 from 710 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.

The final outcome is 2177.17171717, with a leftover of 1.7e-08.
