Let's divide 81143503 by 140
Let's see how many times 140 fits into 81143503.

On to step 1:
When dividing 8 by 140, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 140

On to step 2:
81 divided by 140 is 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 140

Advancing to step 3:
The number 140 fits into 811 5 times, leaving a remainder of 111.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 700 from 811 leaves us with 111.
Grab the next digit (4) from the dividend, add it to 111, then carry on: 1114 / 140

On to step 4:
140 can be fit into 1114 7 times, resulting in a remainder of 134.
Put 7 as the next digit of the answer. 
Result so far: 57.0
If we take 980 away from 1114, we end up with 134.
Bring next digit (3) of the dividend behind the 134 and repeat the process: 1343 / 140

Advancing to step 5:
140 goes into 1343 9 times with a remainder of 83.
Write down 9 as next digit of the result. 
Result so far: 579.0
If we subtract 1260 from 1343, we get 83.
Append the next digit (5) from the dividend to 83 and continue with: 835 / 140

Moving on to step 6:
835 divided by 140 is 5 with a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 5795.0
If we take 700 away from 835, we end up with 135.
Append the next digit (0) from the dividend to 135 and continue with: 1350 / 140

Step 7:
140 can be fit into 1350 9 times, resulting in a remainder of 90.
The number 9 becomes the next digit in our result. 
Result so far: 57959.0
The remainder is 90 after subtracting 1260 from 1350.
Grab the next digit (3) from the dividend, add it to 90, then carry on: 903 / 140

Step 8:
903 divided by 140 is 6 with a remainder of 63.
The next digit of our result is 6. 
Result so far: 579596.0
Deduct 840 from 903 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 9:
When dividing 630 by 140, we get 4 with a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 579596.4
Deduct 560 from 630 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 10:
700 divided by 140 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 579596.45
If we take 700 away from 700, 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.
Use 0 as the next digit of our solution. 
Result so far: 579596.45
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
140 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 579596.45
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.

The quotient of the division is 579596.45, and the remainder is 0.0.
