We look at the division of 623370 by 13 
Our goal is to divide 623370 by 13.

Step 1:
The number 13 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 13

On to step 2:
The number 13 fits into 62 4 times, leaving a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 52 from 62 and we're left with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 13

Step 3:
If we divide 103 by 13, we get 7 and a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we take 91 away from 103, we end up with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 13

Moving on to step 4:
13 goes into 123 9 times with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 479.0
The remainder is 6 after subtracting 117 from 123.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 13

Advancing to step 5:
13 can be fit into 67 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 4795.0
Deduct 65 from 67 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 13

Moving on to step 6:
When dividing 20 by 13, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 47951.0
Deduct 13 from 20 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
If we divide 70 by 13, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 47951.5
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
If we divide 50 by 13, we get 3 and a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 47951.53
If we subtract 39 from 50, we 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.

Advancing to step 9:
The number 13 fits into 110 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 47951.538
Subtract 104 from 110 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
The number 13 fits into 60 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 47951.5384
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
13 can be fit into 80 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 47951.53846
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
20 divided by 13 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 47951.538461
If we subtract 13 from 20, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
When dividing 70 by 13, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 47951.5384615
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
50 divided by 13 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 47951.53846153
Deduct 39 from 50 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.

The quotient of the division is 47951.53846153, and the remainder is 1.1e-08.
