51579103 ÷ 490 
We're looking to find how many times 490 goes into 51579103.

Advancing to step 1:
5 divided by 490 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 490

Let's proceed to step 2:
The number 490 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 490

On to step 3:
515 divided by 490 is 1 with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 490 from 515 and we're left with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 490

Advancing to step 4:
If we divide 257 by 490, we get 0 and a remainder of 257.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 257 after subtracting 0 from 257.
Fetch the next digit (9) from the dividend, attach it to 257 and continue: 2579 / 490

Going ahead to step 5:
If we divide 2579 by 490, we get 5 and a remainder of 129.
Write down 5 as next digit of the result. 
Result so far: 105.0
Deduct 2450 from 2579 and we're left with 129.
Bring next digit (1) of the dividend behind the 129 and repeat the process: 1291 / 490

Step 6:
If we divide 1291 by 490, we get 2 and a remainder of 311.
Put 2 as the next digit of the answer. 
Result so far: 1052.0
If we take 980 away from 1291, we end up with 311.
Fetch the next digit (0) from the dividend, attach it to 311 and continue: 3110 / 490

Moving on to step 7:
If we divide 3110 by 490, we get 6 and a remainder of 170.
Put 6 as the next digit of the answer. 
Result so far: 10526.0
Subtracting 2940 from 3110 leaves us with 170.
Include the next digit (3) from the dividend after 170, then repeat: 1703 / 490

On to step 8:
When dividing 1703 by 490, we get 3 with a remainder of 233.
Use 3 as the next digit of our solution. 
Result so far: 105263.0
If we take 1470 away from 1703, we end up with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 9:
If we divide 2330 by 490, we get 4 and a remainder of 370.
Put 4 as the next digit of the answer. 
Result so far: 105263.4
Subtracting 1960 from 2330 leaves us with 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 10:
When dividing 3700 by 490, we get 7 with a remainder of 270.
The next digit of our result is 7. 
Result so far: 105263.47
Deduct 3430 from 3700 and we're left 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.

Advancing to step 11:
490 goes into 2700 5 times with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 105263.475
Subtract 2450 from 2700 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 12:
The number 490 fits into 2500 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 105263.4755
The remainder is 50 after subtracting 2450 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 105263.4755 and a remainder of 0.0005.
