Let's divide 166425 by 31
We're looking to find how many times 31 goes into 166425.

Moving on to step 1:
The number 31 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 31

Moving on to step 2:
31 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 31

Going ahead to step 3:
31 can be fit into 166 5 times, resulting in a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 155 from 166 and we're left with 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 31

Moving on to step 4:
31 goes into 114 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtracting 93 from 114 leaves us with 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 31

Let's proceed to step 5:
When dividing 212 by 31, we get 6 with a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 536.0
If we subtract 186 from 212, we get 26.
Take the next digit (5) from the dividend and append it to 26, then repeat: 265 / 31

Going ahead to step 6:
When dividing 265 by 31, we get 8 with a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 5368.0
The remainder is 17 after subtracting 248 from 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
31 can be fit into 170 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 5368.5
The remainder is 15 after subtracting 155 from 170.
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 8:
31 goes into 150 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 5368.54
Subtract 124 from 150 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
When dividing 260 by 31, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 5368.548
Subtract 248 from 260 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
120 divided by 31 is 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 5368.5483
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.

Step 11:
31 can be fit into 270 8 times, resulting in a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 5368.54838
Subtracting 248 from 270 leaves us 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.

Step 12:
If we divide 220 by 31, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 5368.548387
If we take 217 away from 220, we end up 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.

Advancing to step 13:
When dividing 30 by 31, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 5368.548387
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.

Step 14:
The number 31 fits into 300 9 times, leaving a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 5368.54838709
Subtract 279 from 300 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 5368.54838709 with a remainder of 2.1e-08.
