We look at the division of 66425 by 31 
Let's see how many times 31 fits into 66425.

Advancing to step 1:
31 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 31

Step 2:
When dividing 66 by 31, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 62 from 66 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 31

Advancing to step 3:
If we divide 44 by 31, we get 1 and a remainder of 13.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 31 from 44, we get 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 31

Advancing to step 4:
The number 31 fits into 132 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 214.0
If we take 124 away from 132, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 31

Going ahead to step 5:
31 goes into 85 2 times with a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 2142.0
Subtract 62 from 85 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 6:
31 goes into 230 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 2142.7
Subtract 217 from 230 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
The number 31 fits into 130 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 2142.74
The remainder is 6 after subtracting 124 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
The number 31 fits into 60 1 times, leaving a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 2142.741
The remainder is 29 after subtracting 31 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
290 divided by 31 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 2142.7419
Deduct 279 from 290 and we're left 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 10:
When dividing 110 by 31, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 2142.74193
If we subtract 93 from 110, we get 17.
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 11:
If we divide 170 by 31, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 2142.741935
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.

Going ahead to step 12:
If we divide 150 by 31, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 2142.7419354
If we take 124 away from 150, we end up 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.

Going ahead to step 13:
31 can be fit into 260 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 2142.74193548
If we subtract 248 from 260, we 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.

The quotient of the division is 2142.74193548, and the remainder is 1.2e-08.
