67911936 ÷ 490 
We want to divide 67911936 by 490.

Step 1:
If we divide 6 by 490, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 490

Step 2:
490 goes into 67 0 times with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Take the next digit (9) from the dividend and append it to 67, then repeat: 679 / 490

Going ahead to step 3:
490 can be fit into 679 1 times, resulting in a remainder of 189.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 490 from 679, we get 189.
Fetch the next digit (1) from the dividend, attach it to 189 and continue: 1891 / 490

Going ahead to step 4:
490 goes into 1891 3 times with a remainder of 421.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 1470 from 1891 leaves us with 421.
Bring next digit (1) of the dividend behind the 421 and repeat the process: 4211 / 490

Advancing to step 5:
If we divide 4211 by 490, we get 8 and a remainder of 291.
The next digit of our result is 8. 
Result so far: 138.0
Deduct 3920 from 4211 and we're left with 291.
Fetch the next digit (9) from the dividend, attach it to 291 and continue: 2919 / 490

Step 6:
If we divide 2919 by 490, we get 5 and a remainder of 469.
Record the quotient 5 as the next digit in the result. 
Result so far: 1385.0
Deduct 2450 from 2919 and we're left with 469.
Take the next digit (3) from the dividend and append it to 469, then repeat: 4693 / 490

Step 7:
If we divide 4693 by 490, we get 9 and a remainder of 283.
Write down 9 as next digit of the result. 
Result so far: 13859.0
Deduct 4410 from 4693 and we're left with 283.
Bring next digit (6) of the dividend behind the 283 and repeat the process: 2836 / 490

Let's proceed to step 8:
The number 490 fits into 2836 5 times, leaving a remainder of 386.
Put 5 as the next digit of the answer. 
Result so far: 138595.0
The remainder is 386 after subtracting 2450 from 2836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 9:
When dividing 3860 by 490, we get 7 with a remainder of 430.
Use 7 as the next digit of our solution. 
Result so far: 138595.7
The remainder is 430 after subtracting 3430 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 10:
4300 divided by 490 is 8 with a remainder of 380.
Use 8 as the next digit of our solution. 
Result so far: 138595.78
Subtract 3920 from 4300 to 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.

Going ahead to step 11:
490 can be fit into 3800 7 times, resulting in a remainder of 370.
Record the quotient 7 as the next digit in the result. 
Result so far: 138595.787
Deduct 3430 from 3800 and we're left 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 12:
490 goes into 3700 7 times with a remainder of 270.
The next digit of our result is 7. 
Result so far: 138595.7877
Subtract 3430 from 3700 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The final outcome is 138595.7877, with a leftover of 0.0027.
