We're dividing 141872 by 31 
Let's see how many times 31 fits into 141872.

Moving on to step 1:
When dividing 1 by 31, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 31

Advancing to step 2:
31 goes into 14 0 times with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 31

Let's proceed to step 3:
141 divided by 31 is 4 with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 124 from 141 to get 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 31

Step 4:
178 divided by 31 is 5 with a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtract 155 from 178 to get 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 31

Let's proceed to step 5:
31 can be fit into 237 7 times, resulting in a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 457.0
The remainder is 20 after subtracting 217 from 237.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 31

On to step 6:
If we divide 202 by 31, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 4576.0
The remainder is 16 after subtracting 186 from 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
If we divide 160 by 31, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4576.5
Subtracting 155 from 160 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
50 divided by 31 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 4576.51
If we take 31 away from 50, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
31 goes into 190 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 4576.516
Subtracting 186 from 190 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
The number 31 fits into 40 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 4576.5161
Deduct 31 from 40 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 11:
The number 31 fits into 90 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 4576.51612
The remainder is 28 after subtracting 62 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
If we divide 280 by 31, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 4576.516129
If we subtract 279 from 280, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 13:
When dividing 10 by 31, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 4576.516129
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
If we divide 100 by 31, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 4576.51612903
Subtracting 93 from 100 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 4576.51612903 with a remainder of 7e-09.
