We're dividing 68170535 by 490 
Our goal is to divide 68170535 by 490.

Going ahead to step 1:
490 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 490

On to step 2:
490 can be fit into 68 0 times, resulting in a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Fetch the next digit (1) from the dividend, attach it to 68 and continue: 681 / 490

Advancing to step 3:
When dividing 681 by 490, we get 1 with a remainder of 191.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 490 from 681 and we're left with 191.
Fetch the next digit (7) from the dividend, attach it to 191 and continue: 1917 / 490

On to step 4:
If we divide 1917 by 490, we get 3 and a remainder of 447.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 1470 from 1917 and we're left with 447.
Append the next digit (0) from the dividend to 447 and continue with: 4470 / 490

Advancing to step 5:
490 can be fit into 4470 9 times, resulting in a remainder of 60.
Put 9 as the next digit of the answer. 
Result so far: 139.0
Subtract 4410 from 4470 to get 60.
Grab the next digit (5) from the dividend, add it to 60, then carry on: 605 / 490

Step 6:
When dividing 605 by 490, we get 1 with a remainder of 115.
The number 1 becomes the next digit in our result. 
Result so far: 1391.0
The remainder is 115 after subtracting 490 from 605.
Fetch the next digit (3) from the dividend, attach it to 115 and continue: 1153 / 490

Step 7:
490 can be fit into 1153 2 times, resulting in a remainder of 173.
Write down 2 as next digit of the result. 
Result so far: 13912.0
If we subtract 980 from 1153, we get 173.
Take the next digit (5) from the dividend and append it to 173, then repeat: 1735 / 490

Moving on to step 8:
490 can be fit into 1735 3 times, resulting in a remainder of 265.
Put 3 as the next digit of the answer. 
Result so far: 139123.0
Subtract 1470 from 1735 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 9:
The number 490 fits into 2650 5 times, leaving a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 139123.5
Subtracting 2450 from 2650 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 10:
2000 divided by 490 is 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 139123.54
The remainder is 40 after subtracting 1960 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
The number 490 fits into 400 0 times, leaving a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 139123.54
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 12:
If we divide 4000 by 490, we get 8 and a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 139123.5408
Subtract 3920 from 4000 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
490 can be fit into 800 1 times, resulting in a remainder of 310.
Record the quotient 1 as the next digit in the result. 
Result so far: 139123.54081
If we subtract 490 from 800, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 14:
490 can be fit into 3100 6 times, resulting in a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 139123.540816
If we take 2940 away from 3100, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 15:
490 goes into 1600 3 times with a remainder of 130.
The next digit of our result is 3. 
Result so far: 139123.5408163
Deduct 1470 from 1600 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 16:
When dividing 1300 by 490, we get 2 with a remainder of 320.
Write down 2 as next digit of the result. 
Result so far: 139123.54081632
If we take 980 away from 1300, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Our division results in 139123.54081632 with a remaining 3.2e-07.
