71992390 divided by 490 
We want to figure out the number of times 71992390 can be divided by 490.

Moving on to step 1:
When dividing 7 by 490, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 490

On to step 2:
490 can be fit into 71 0 times, resulting in a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Take the next digit (9) from the dividend and append it to 71, then repeat: 719 / 490

On to step 3:
When dividing 719 by 490, we get 1 with a remainder of 229.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 490 from 719, we get 229.
Take the next digit (9) from the dividend and append it to 229, then repeat: 2299 / 490

Going ahead to step 4:
490 goes into 2299 4 times with a remainder of 339.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 1960 from 2299 and we're left with 339.
Include the next digit (2) from the dividend after 339, then repeat: 3392 / 490

Going ahead to step 5:
The number 490 fits into 3392 6 times, leaving a remainder of 452.
The next digit of our result is 6. 
Result so far: 146.0
Subtract 2940 from 3392 to get 452.
Grab the next digit (3) from the dividend, add it to 452, then carry on: 4523 / 490

Advancing to step 6:
If we divide 4523 by 490, we get 9 and a remainder of 113.
Record the quotient 9 as the next digit in the result. 
Result so far: 1469.0
The remainder is 113 after subtracting 4410 from 4523.
Fetch the next digit (9) from the dividend, attach it to 113 and continue: 1139 / 490

Moving on to step 7:
490 goes into 1139 2 times with a remainder of 159.
Write down 2 as next digit of the result. 
Result so far: 14692.0
If we take 980 away from 1139, we end up with 159.
Take the next digit (0) from the dividend and append it to 159, then repeat: 1590 / 490

Moving on to step 8:
490 goes into 1590 3 times with a remainder of 120.
Put 3 as the next digit of the answer. 
Result so far: 146923.0
The remainder is 120 after subtracting 1470 from 1590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 9:
The number 490 fits into 1200 2 times, leaving a remainder of 220.
Write down 2 as next digit of the result. 
Result so far: 146923.2
Subtract 980 from 1200 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 10:
When dividing 2200 by 490, we get 4 with a remainder of 240.
Write down 4 as next digit of the result. 
Result so far: 146923.24
Subtracting 1960 from 2200 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 11:
The number 490 fits into 2400 4 times, leaving a remainder of 440.
Write down 4 as next digit of the result. 
Result so far: 146923.244
If we take 1960 away from 2400, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Our division results in 146923.244 with a remaining 0.044.
