Let's divide 72103831 by 141
We want to figure out the number of times 72103831 can be divided by 141.

Let's proceed to step 1:
The number 141 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 141

Going ahead to step 2:
141 goes into 72 0 times with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 141

Advancing to step 3:
141 goes into 721 5 times with a remainder of 16.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 705 from 721 leaves us with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 141

On to step 4:
If we divide 160 by 141, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 51.0
If we take 141 away from 160, we end up with 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 141

Step 5:
193 divided by 141 is 1 with a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 511.0
Subtracting 141 from 193 leaves us with 52.
Include the next digit (8) from the dividend after 52, then repeat: 528 / 141

Step 6:
If we divide 528 by 141, we get 3 and a remainder of 105.
Write down 3 as next digit of the result. 
Result so far: 5113.0
If we take 423 away from 528, we end up with 105.
Append the next digit (3) from the dividend to 105 and continue with: 1053 / 141

Let's proceed to step 7:
If we divide 1053 by 141, we get 7 and a remainder of 66.
Put 7 as the next digit of the answer. 
Result so far: 51137.0
If we take 987 away from 1053, we end up with 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 141

Advancing to step 8:
141 can be fit into 661 4 times, resulting in a remainder of 97.
Use 4 as the next digit of our solution. 
Result so far: 511374.0
The remainder is 97 after subtracting 564 from 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Let's proceed to step 9:
The number 141 fits into 970 6 times, leaving a remainder of 124.
The number 6 becomes the next digit in our result. 
Result so far: 511374.6
If we subtract 846 from 970, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 10:
When dividing 1240 by 141, we get 8 with a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 511374.68
The remainder is 112 after subtracting 1128 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 11:
141 goes into 1120 7 times with a remainder of 133.
Put 7 as the next digit of the answer. 
Result so far: 511374.687
If we subtract 987 from 1120, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 12:
1330 divided by 141 is 9 with a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 511374.6879
If we subtract 1269 from 1330, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 13:
610 divided by 141 is 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 511374.68794
Deduct 564 from 610 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 14:
When dividing 460 by 141, we get 3 with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 511374.687943
If we take 423 away from 460, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 15:
141 goes into 370 2 times with a remainder of 88.
The next digit of our result is 2. 
Result so far: 511374.6879432
Subtracting 282 from 370 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 16:
880 divided by 141 is 6 with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 511374.68794326
Subtract 846 from 880 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 511374.68794326 and a remainder of 3.4e-08.
