Let's divide 191491 by 31
Let's see how many times 31 fits into 191491.

Step 1:
The number 31 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 31

Going ahead to step 2:
31 can be fit into 19 0 times, resulting in a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 31

Moving on to step 3:
When dividing 191 by 31, we get 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 186 from 191 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 31

On to step 4:
When dividing 54 by 31, we get 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 61.0
Subtracting 31 from 54 leaves us with 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 31

Going ahead to step 5:
239 divided by 31 is 7 with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 617.0
Subtract 217 from 239 to get 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 31

On to step 6:
When dividing 221 by 31, we get 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 6177.0
The remainder is 4 after subtracting 217 from 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
If we divide 40 by 31, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 6177.1
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.

Advancing to step 8:
31 can be fit into 90 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 6177.12
Subtracting 62 from 90 leaves us 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.

Let's proceed to step 9:
If we divide 280 by 31, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 6177.129
If we take 279 away from 280, we end up 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.

On to step 10:
If we divide 10 by 31, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 6177.129
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.

Going ahead to step 11:
When dividing 100 by 31, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 6177.12903
If we subtract 93 from 100, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
When dividing 70 by 31, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 6177.129032
Deduct 62 from 70 and we're left with 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:
The number 31 fits into 80 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 6177.1290322
If we subtract 62 from 80, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 6177.1290322, with a leftover of 1.8e-07.
