We look at the division of 12894143 by 620 
We're looking to find how many times 620 goes into 12894143.

Moving on to step 1:
1 divided by 620 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 620

Let's proceed to step 2:
620 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 620

Step 3:
128 divided by 620 is 0 with a remainder of 128.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 128 leaves us with 128.
Fetch the next digit (9) from the dividend, attach it to 128 and continue: 1289 / 620

Let's proceed to step 4:
620 can be fit into 1289 2 times, resulting in a remainder of 49.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1240 from 1289 and we're left with 49.
Bring next digit (4) of the dividend behind the 49 and repeat the process: 494 / 620

Step 5:
When dividing 494 by 620, we get 0 with a remainder of 494.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we subtract 0 from 494, we get 494.
Bring next digit (1) of the dividend behind the 494 and repeat the process: 4941 / 620

Going ahead to step 6:
The number 620 fits into 4941 7 times, leaving a remainder of 601.
Put 7 as the next digit of the answer. 
Result so far: 207.0
Deduct 4340 from 4941 and we're left with 601.
Fetch the next digit (4) from the dividend, attach it to 601 and continue: 6014 / 620

Advancing to step 7:
620 can be fit into 6014 9 times, resulting in a remainder of 434.
The next digit of our result is 9. 
Result so far: 2079.0
If we take 5580 away from 6014, we end up with 434.
Include the next digit (3) from the dividend after 434, then repeat: 4343 / 620

Step 8:
The number 620 fits into 4343 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 20797.0
Deduct 4340 from 4343 and we're left 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.

Let's proceed to step 9:
When dividing 30 by 620, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 20797.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
If we divide 300 by 620, we get 0 and a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 20797.0
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 20797.0 with a remaining 0.3.
