We look at the division of 6402291 by 140 
We want to divide 6402291 by 140.

Going ahead to step 1:
When dividing 6 by 140, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 140

Going ahead to step 2:
140 can be fit into 64 0 times, resulting in a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 140

Let's proceed to step 3:
When dividing 640 by 140, we get 4 with a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 560 from 640 to get 80.
Fetch the next digit (2) from the dividend, attach it to 80 and continue: 802 / 140

Let's proceed to step 4:
140 goes into 802 5 times with a remainder of 102.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtracting 700 from 802 leaves us with 102.
Take the next digit (2) from the dividend and append it to 102, then repeat: 1022 / 140

On to step 5:
1022 divided by 140 is 7 with a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 457.0
If we take 980 away from 1022, we end up with 42.
Fetch the next digit (9) from the dividend, attach it to 42 and continue: 429 / 140

Going ahead to step 6:
If we divide 429 by 140, we get 3 and a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 4573.0
Subtract 420 from 429 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 140

Advancing to step 7:
140 can be fit into 91 0 times, resulting in a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 45730.0
Subtract 0 from 91 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 8:
140 can be fit into 910 6 times, resulting in a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 45730.6
Deduct 840 from 910 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
If we divide 700 by 140, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 45730.65
Subtracting 700 from 700 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
0 divided by 140 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 45730.65
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
The number 140 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 45730.65
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 45730.65, with a leftover of 0.0.
