Let's divide 70770393 by 490
Let's see how many times 490 fits into 70770393.

Advancing to step 1:
If we divide 7 by 490, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 490

Step 2:
If we divide 70 by 490, we get 0 and a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Append the next digit (7) from the dividend to 70 and continue with: 707 / 490

Going ahead to step 3:
490 can be fit into 707 1 times, resulting in a remainder of 217.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 490 away from 707, we end up with 217.
Include the next digit (7) from the dividend after 217, then repeat: 2177 / 490

On to step 4:
2177 divided by 490 is 4 with a remainder of 217.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 1960 away from 2177, we end up with 217.
Bring next digit (0) of the dividend behind the 217 and repeat the process: 2170 / 490

Step 5:
When dividing 2170 by 490, we get 4 with a remainder of 210.
The next digit of our result is 4. 
Result so far: 144.0
Subtract 1960 from 2170 to get 210.
Include the next digit (3) from the dividend after 210, then repeat: 2103 / 490

Moving on to step 6:
The number 490 fits into 2103 4 times, leaving a remainder of 143.
Put 4 as the next digit of the answer. 
Result so far: 1444.0
Deduct 1960 from 2103 and we're left with 143.
Bring next digit (9) of the dividend behind the 143 and repeat the process: 1439 / 490

Moving on to step 7:
490 can be fit into 1439 2 times, resulting in a remainder of 459.
The next digit of our result is 2. 
Result so far: 14442.0
The remainder is 459 after subtracting 980 from 1439.
Take the next digit (3) from the dividend and append it to 459, then repeat: 4593 / 490

Going ahead to step 8:
490 goes into 4593 9 times with a remainder of 183.
Use 9 as the next digit of our solution. 
Result so far: 144429.0
Deduct 4410 from 4593 and we're left with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

On to step 9:
1830 divided by 490 is 3 with a remainder of 360.
Record the quotient 3 as the next digit in the result. 
Result so far: 144429.3
If we take 1470 away from 1830, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 10:
If we divide 3600 by 490, we get 7 and a remainder of 170.
Write down 7 as next digit of the result. 
Result so far: 144429.37
If we subtract 3430 from 3600, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 11:
When dividing 1700 by 490, we get 3 with a remainder of 230.
The next digit of our result is 3. 
Result so far: 144429.373
If we subtract 1470 from 1700, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 12:
When dividing 2300 by 490, we get 4 with a remainder of 340.
Write down 4 as next digit of the result. 
Result so far: 144429.3734
Subtract 1960 from 2300 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 13:
490 can be fit into 3400 6 times, resulting in a remainder of 460.
Use 6 as the next digit of our solution. 
Result so far: 144429.37346
Subtracting 2940 from 3400 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 14:
If we divide 4600 by 490, we get 9 and a remainder of 190.
Use 9 as the next digit of our solution. 
Result so far: 144429.373469
If we subtract 4410 from 4600, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 15:
If we divide 1900 by 490, we get 3 and a remainder of 430.
Put 3 as the next digit of the answer. 
Result so far: 144429.3734693
If we subtract 1470 from 1900, we 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.

On to step 16:
The number 490 fits into 4300 8 times, leaving a remainder of 380.
Record the quotient 8 as the next digit in the result. 
Result so far: 144429.37346938
If we subtract 3920 from 4300, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Our division results in 144429.37346938 with a remaining 3.8e-07.
