Let's divide 187809 by 31
We want to divide 187809 by 31.

On to step 1:
31 goes into 1 0 times with 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.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 31

On to step 2:
The number 31 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 31

On to step 3:
If we divide 187 by 31, we get 6 and a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 186 from 187 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 31

Moving on to step 4:
18 divided by 31 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Subtract 0 from 18 to get 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 31

Moving on to step 5:
31 can be fit into 180 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 605.0
If we take 155 away from 180, we end up with 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 31

Let's proceed to step 6:
31 can be fit into 259 8 times, resulting in a remainder of 11.
The next digit of our result is 8. 
Result so far: 6058.0
If we take 248 away from 259, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
When dividing 110 by 31, we get 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 6058.3
The remainder is 17 after subtracting 93 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
31 can be fit into 170 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 6058.35
If we subtract 155 from 170, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
31 goes into 150 4 times with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 6058.354
Subtracting 124 from 150 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
260 divided by 31 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 6058.3548
If we take 248 away from 260, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
If we divide 120 by 31, we get 3 and a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 6058.35483
Subtract 93 from 120 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 12:
If we divide 270 by 31, we get 8 and a remainder of 22.
The next digit of our result is 8. 
Result so far: 6058.354838
Deduct 248 from 270 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
When dividing 220 by 31, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 6058.3548387
Deduct 217 from 220 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 14:
31 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 6058.3548387
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 6058.3548387, with a leftover of 3e-08.
