We're dividing 21290078 by 299 
We want to figure out the number of times 21290078 can be divided by 299.

Advancing to step 1:
The number 299 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
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 / 299

Advancing to step 2:
When dividing 21 by 299, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 299

Let's proceed to step 3:
299 goes into 212 0 times with a remainder of 212.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 212 leaves us with 212.
Include the next digit (9) from the dividend after 212, then repeat: 2129 / 299

Let's proceed to step 4:
2129 divided by 299 is 7 with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 2093 from 2129 to get 36.
Bring next digit (0) of the dividend behind the 36 and repeat the process: 360 / 299

Let's proceed to step 5:
If we divide 360 by 299, we get 1 and a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 71.0
The remainder is 61 after subtracting 299 from 360.
Take the next digit (0) from the dividend and append it to 61, then repeat: 610 / 299

On to step 6:
299 can be fit into 610 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 712.0
If we take 598 away from 610, we end up with 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 299

Going ahead to step 7:
127 divided by 299 is 0 with a remainder of 127.
The number 0 becomes the next digit in our result. 
Result so far: 7120.0
If we subtract 0 from 127, we get 127.
Grab the next digit (8) from the dividend, add it to 127, then carry on: 1278 / 299

Advancing to step 8:
1278 divided by 299 is 4 with a remainder of 82.
The number 4 becomes the next digit in our result. 
Result so far: 71204.0
If we take 1196 away from 1278, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
299 goes into 820 2 times with a remainder of 222.
Put 2 as the next digit of the answer. 
Result so far: 71204.2
Subtract 598 from 820 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 10:
299 goes into 2220 7 times with a remainder of 127.
The next digit of our result is 7. 
Result so far: 71204.27
If we subtract 2093 from 2220, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 11:
When dividing 1270 by 299, we get 4 with a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 71204.274
If we take 1196 away from 1270, 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.

Let's proceed to step 12:
299 goes into 740 2 times with a remainder of 142.
Use 2 as the next digit of our solution. 
Result so far: 71204.2742
Subtract 598 from 740 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 13:
The number 299 fits into 1420 4 times, leaving a remainder of 224.
Use 4 as the next digit of our solution. 
Result so far: 71204.27424
If we take 1196 away from 1420, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 14:
When dividing 2240 by 299, we get 7 with a remainder of 147.
Use 7 as the next digit of our solution. 
Result so far: 71204.274247
If we subtract 2093 from 2240, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 15:
The number 299 fits into 1470 4 times, leaving a remainder of 274.
The number 4 becomes the next digit in our result. 
Result so far: 71204.2742474
Subtract 1196 from 1470 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 16:
When dividing 2740 by 299, we get 9 with a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 71204.27424749
Deduct 2691 from 2740 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

After the division, we end up with 71204.27424749 and a remainder of 4.9e-08.
