Let's proceed to step 4:
If we divide 2170 by 990, we get 2 and a remainder of 190.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1980 from 2170 and we're left with 190.
Grab the next digit (5) from the dividend, add it to 190, then carry on: 1905 / 990

Advancing to step 5:
990 can be fit into 1905 1 times, resulting in a remainder of 915.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtracting 990 from 1905 leaves us with 915.
Append the next digit (3) from the dividend to 915 and continue with: 9153 / 990

Going ahead to step 6:
When dividing 9153 by 990, we get 9 with a remainder of 243.
The number 9 becomes the next digit in our result. 
Result so far: 219.0
If we subtract 8910 from 9153, we get 243.
Take the next digit (1) from the dividend and append it to 243, then repeat: 2431 / 990

Let's proceed to step 7:
If we divide 2431 by 990, we get 2 and a remainder of 451.
Write down 2 as next digit of the result. 
Result so far: 2192.0
Deduct 1980 from 2431 and we're left with 451.
Append the next digit (7) from the dividend to 451 and continue with: 4517 / 990

Let's proceed to step 8:
990 can be fit into 4517 4 times, resulting in a remainder of 557.
Put 4 as the next digit of the answer. 
Result so far: 21924.0
The remainder is 557 after subtracting 3960 from 4517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Advancing to step 9:
990 goes into 5570 5 times with a remainder of 620.
Put 5 as the next digit of the answer. 
Result so far: 21924.5
Subtracting 4950 from 5570 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 10:
990 can be fit into 6200 6 times, resulting in a remainder of 260.
The number 6 becomes the next digit in our result. 
Result so far: 21924.56
If we take 5940 away from 6200, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 11:
If we divide 2600 by 990, we get 2 and a remainder of 620.
The next digit of our result is 2. 
Result so far: 21924.562
Deduct 1980 from 2600 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 12:
990 can be fit into 6200 6 times, resulting in a remainder of 260.
The number 6 becomes the next digit in our result. 
Result so far: 21924.5626
Subtracting 5940 from 6200 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 13:
When dividing 2600 by 990, we get 2 with a remainder of 620.
Put 2 as the next digit of the answer. 
Result so far: 21924.56262
Deduct 1980 from 2600 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 14:
If we divide 6200 by 990, we get 6 and a remainder of 260.
The next digit of our result is 6. 
Result so far: 21924.562626
If we take 5940 away from 6200, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 15:
If we divide 2600 by 990, we get 2 and a remainder of 620.
The number 2 becomes the next digit in our result. 
Result so far: 21924.5626262
Subtract 1980 from 2600 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 16:
6200 divided by 990 is 6 with a remainder of 260.
Write down 6 as next digit of the result. 
Result so far: 21924.56262626
The remainder is 260 after subtracting 5940 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 21924.56262626, with a leftover of 2.6e-07.
