71615151 divided by 490 
We want to figure out the number of times 71615151 can be divided by 490.

On to step 1:
If we divide 7 by 490, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 490

On to step 2:
If we divide 71 by 490, we get 0 and a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Append the next digit (6) from the dividend to 71 and continue with: 716 / 490

Step 3:
If we divide 716 by 490, we get 1 and a remainder of 226.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 490 from 716 and we're left with 226.
Fetch the next digit (1) from the dividend, attach it to 226 and continue: 2261 / 490

Advancing to step 4:
If we divide 2261 by 490, we get 4 and a remainder of 301.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 301 after subtracting 1960 from 2261.
Include the next digit (5) from the dividend after 301, then repeat: 3015 / 490

Step 5:
490 can be fit into 3015 6 times, resulting in a remainder of 75.
Put 6 as the next digit of the answer. 
Result so far: 146.0
If we take 2940 away from 3015, we end up with 75.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 490

On to step 6:
751 divided by 490 is 1 with a remainder of 261.
Put 1 as the next digit of the answer. 
Result so far: 1461.0
If we take 490 away from 751, we end up with 261.
Take the next digit (5) from the dividend and append it to 261, then repeat: 2615 / 490

Let's proceed to step 7:
490 can be fit into 2615 5 times, resulting in a remainder of 165.
Record the quotient 5 as the next digit in the result. 
Result so far: 14615.0
Subtract 2450 from 2615 to get 165.
Grab the next digit (1) from the dividend, add it to 165, then carry on: 1651 / 490

Moving on to step 8:
490 can be fit into 1651 3 times, resulting in a remainder of 181.
Write down 3 as next digit of the result. 
Result so far: 146153.0
If we subtract 1470 from 1651, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 9:
If we divide 1810 by 490, we get 3 and a remainder of 340.
Record the quotient 3 as the next digit in the result. 
Result so far: 146153.3
Subtracting 1470 from 1810 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 10:
3400 divided by 490 is 6 with a remainder of 460.
The next digit of our result is 6. 
Result so far: 146153.36
If we subtract 2940 from 3400, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 11:
If we divide 4600 by 490, we get 9 and a remainder of 190.
Put 9 as the next digit of the answer. 
Result so far: 146153.369
Deduct 4410 from 4600 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 12:
If we divide 1900 by 490, we get 3 and a remainder of 430.
Write down 3 as next digit of the result. 
Result so far: 146153.3693
Subtract 1470 from 1900 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 13:
490 goes into 4300 8 times with a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 146153.36938
If we take 3920 away from 4300, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 14:
490 goes into 3800 7 times with a remainder of 370.
Write down 7 as next digit of the result. 
Result so far: 146153.369387
Subtract 3430 from 3800 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 15:
490 can be fit into 3700 7 times, resulting in a remainder of 270.
Write down 7 as next digit of the result. 
Result so far: 146153.3693877
Subtracting 3430 from 3700 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Our division results in 146153.3693877 with a remaining 2.7e-06.
