21995590 ÷ 284 
We want to figure out the number of times 21995590 can be divided by 284.

On to step 1:
When dividing 2 by 284, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 284

Step 2:
If we divide 21 by 284, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 284

Moving on to step 3:
When dividing 219 by 284, we get 0 with a remainder of 219.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 219, we get 219.
Append the next digit (9) from the dividend to 219 and continue with: 2199 / 284

Step 4:
The number 284 fits into 2199 7 times, leaving a remainder of 211.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 1988 from 2199 leaves us with 211.
Include the next digit (5) from the dividend after 211, then repeat: 2115 / 284

Let's proceed to step 5:
2115 divided by 284 is 7 with a remainder of 127.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
If we subtract 1988 from 2115, we get 127.
Bring next digit (5) of the dividend behind the 127 and repeat the process: 1275 / 284

Let's proceed to step 6:
1275 divided by 284 is 4 with a remainder of 139.
Write down 4 as next digit of the result. 
Result so far: 774.0
The remainder is 139 after subtracting 1136 from 1275.
Take the next digit (9) from the dividend and append it to 139, then repeat: 1399 / 284

Let's proceed to step 7:
284 goes into 1399 4 times with a remainder of 263.
Record the quotient 4 as the next digit in the result. 
Result so far: 7744.0
Subtracting 1136 from 1399 leaves us with 263.
Include the next digit (0) from the dividend after 263, then repeat: 2630 / 284

Let's proceed to step 8:
When dividing 2630 by 284, we get 9 with a remainder of 74.
Put 9 as the next digit of the answer. 
Result so far: 77449.0
If we take 2556 away from 2630, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 9:
284 can be fit into 740 2 times, resulting in a remainder of 172.
Put 2 as the next digit of the answer. 
Result so far: 77449.2
If we take 568 away from 740, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 10:
When dividing 1720 by 284, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 77449.26
Subtract 1704 from 1720 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
284 goes into 160 0 times with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 77449.26
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 12:
1600 divided by 284 is 5 with a remainder of 180.
Put 5 as the next digit of the answer. 
Result so far: 77449.2605
Subtracting 1420 from 1600 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 13:
When dividing 1800 by 284, we get 6 with a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 77449.26056
Subtract 1704 from 1800 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 14:
960 divided by 284 is 3 with a remainder of 108.
Put 3 as the next digit of the answer. 
Result so far: 77449.260563
The remainder is 108 after subtracting 852 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 15:
284 goes into 1080 3 times with a remainder of 228.
Write down 3 as next digit of the result. 
Result so far: 77449.2605633
If we subtract 852 from 1080, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

The final result is 77449.2605633 with a remainder of 2.28e-06.
