We look at the division of 141891 by 31 
Let's see how many times 31 fits into 141891.

Going ahead to step 1:
1 divided by 31 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 31

Advancing to step 2:
When dividing 14 by 31, we get 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 31

Moving on to step 3:
The number 31 fits into 141 4 times, leaving a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 17 after subtracting 124 from 141.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 31

Advancing to step 4:
31 can be fit into 178 5 times, resulting in a remainder of 23.
The next digit of our result is 5. 
Result so far: 45.0
Subtracting 155 from 178 leaves us with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 31

Advancing to step 5:
31 goes into 239 7 times with a remainder of 22.
The next digit of our result is 7. 
Result so far: 457.0
If we take 217 away from 239, we end up with 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 31

Advancing to step 6:
When dividing 221 by 31, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 4577.0
If we subtract 217 from 221, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
31 goes into 40 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 4577.1
Subtracting 31 from 40 leaves us 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 8:
If we divide 90 by 31, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 4577.12
If we take 62 away from 90, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
31 can be fit into 280 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 4577.129
Deduct 279 from 280 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
31 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 4577.129
Subtracting 0 from 10 leaves us 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.

Moving on to step 11:
When dividing 100 by 31, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 4577.12903
The remainder is 7 after subtracting 93 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
When dividing 70 by 31, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 4577.129032
If we subtract 62 from 70, 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.

Advancing to step 13:
31 goes into 80 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 4577.1290322
If we take 62 away from 80, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 4577.1290322 and a remainder of 1.8e-07.
