81197628 divided by 140 
We want to divide 81197628 by 140.

Moving on to step 1:
When dividing 8 by 140, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 140

Let's proceed to step 2:
If we divide 81 by 140, we get 0 and a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (1) from the dividend after 81, then repeat: 811 / 140

Moving on to step 3:
140 can be fit into 811 5 times, resulting in a remainder of 111.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 111 after subtracting 700 from 811.
Include the next digit (9) from the dividend after 111, then repeat: 1119 / 140

Step 4:
The number 140 fits into 1119 7 times, leaving a remainder of 139.
Use 7 as the next digit of our solution. 
Result so far: 57.0
The remainder is 139 after subtracting 980 from 1119.
Grab the next digit (7) from the dividend, add it to 139, then carry on: 1397 / 140

On to step 5:
140 can be fit into 1397 9 times, resulting in a remainder of 137.
The number 9 becomes the next digit in our result. 
Result so far: 579.0
Subtract 1260 from 1397 to get 137.
Include the next digit (6) from the dividend after 137, then repeat: 1376 / 140

Moving on to step 6:
If we divide 1376 by 140, we get 9 and a remainder of 116.
Record the quotient 9 as the next digit in the result. 
Result so far: 5799.0
Subtracting 1260 from 1376 leaves us with 116.
Bring next digit (2) of the dividend behind the 116 and repeat the process: 1162 / 140

Let's proceed to step 7:
If we divide 1162 by 140, we get 8 and a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 57998.0
Deduct 1120 from 1162 and we're left with 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 140

Going ahead to step 8:
The number 140 fits into 428 3 times, leaving a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 579983.0
If we subtract 420 from 428, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
If we divide 80 by 140, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 579983.0
If we subtract 0 from 80, we 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.

Moving on to step 10:
When dividing 800 by 140, we get 5 with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 579983.05
Subtract 700 from 800 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
The number 140 fits into 1000 7 times, leaving a remainder of 20.
The next digit of our result is 7. 
Result so far: 579983.057
If we take 980 away from 1000, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
140 goes into 200 1 times with a remainder of 60.
Put 1 as the next digit of the answer. 
Result so far: 579983.0571
The remainder is 60 after subtracting 140 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
600 divided by 140 is 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 579983.05714
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
The number 140 fits into 400 2 times, leaving a remainder of 120.
Use 2 as the next digit of our solution. 
Result so far: 579983.057142
Subtracting 280 from 400 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 15:
140 goes into 1200 8 times with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 579983.0571428
If we subtract 1120 from 1200, we 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.

Advancing to step 16:
The number 140 fits into 800 5 times, leaving a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 579983.05714285
Deduct 700 from 800 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 579983.05714285 with a remainder of 1e-07.
