We look at the division of 143445 by 31 
Our goal is to divide 143445 by 31.

Let's proceed to step 1:
1 divided by 31 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 31

Let's proceed to step 2:
If we divide 14 by 31, we get 0 and a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 31

Step 3:
31 can be fit into 143 4 times, resulting in a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 124 from 143 leaves us with 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 31

Advancing to step 4:
If we divide 194 by 31, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 46.0
The remainder is 8 after subtracting 186 from 194.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 31

Moving on to step 5:
84 divided by 31 is 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 462.0
Subtracting 62 from 84 leaves us with 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 31

Advancing to step 6:
If we divide 225 by 31, we get 7 and a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 4627.0
If we take 217 away from 225, we end up 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.

Going ahead to step 7:
If we divide 80 by 31, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 4627.2
Deduct 62 from 80 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
When dividing 180 by 31, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 4627.25
Subtracting 155 from 180 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
31 goes into 250 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 4627.258
The remainder is 2 after subtracting 248 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
20 divided by 31 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 4627.258
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
200 divided by 31 is 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 4627.25806
If we take 186 away from 200, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
When dividing 140 by 31, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 4627.258064
Subtracting 124 from 140 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
If we divide 160 by 31, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 4627.2580645
Subtract 155 from 160 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
50 divided by 31 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 4627.25806451
Deduct 31 from 50 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 4627.25806451, and the remainder is 1.9e-08.
