Let's divide 148620 by 31
Let's see how many times 31 fits into 148620.

Step 1:
31 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 31

Going ahead to step 2:
14 divided by 31 is 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 31

Advancing to step 3:
When dividing 148 by 31, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 124 from 148 to get 24.
Fetch the next digit (6) from the dividend, attach it to 24 and continue: 246 / 31

Moving on to step 4:
The number 31 fits into 246 7 times, leaving a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
The remainder is 29 after subtracting 217 from 246.
Append the next digit (2) from the dividend to 29 and continue with: 292 / 31

On to step 5:
If we divide 292 by 31, we get 9 and a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 479.0
Subtracting 279 from 292 leaves us with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 31

On to step 6:
130 divided by 31 is 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 4794.0
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.

On to step 7:
When dividing 60 by 31, we get 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 4794.1
If we take 31 away from 60, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 8:
290 divided by 31 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 4794.19
Subtract 279 from 290 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
If we divide 110 by 31, we get 3 and a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 4794.193
Deduct 93 from 110 and we're left with 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 10:
When dividing 170 by 31, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 4794.1935
Subtracting 155 from 170 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
The number 31 fits into 150 4 times, leaving a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 4794.19354
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.

On to step 12:
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: 4794.193548
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.

Let's proceed to step 13:
The number 31 fits into 120 3 times, leaving a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 4794.1935483
Deduct 93 from 120 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 14:
When dividing 270 by 31, we get 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 4794.19354838
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.

The quotient of the division is 4794.19354838, and the remainder is 2.2e-08.
