We're dividing 8139956 by 389 
Our goal is to divide 8139956 by 389.

Step 1:
8 divided by 389 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 389

Moving on to step 2:
389 can be fit into 81 0 times, resulting in a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 389

Advancing to step 3:
389 can be fit into 813 2 times, resulting in a remainder of 35.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 778 from 813 leaves us with 35.
Grab the next digit (9) from the dividend, add it to 35, then carry on: 359 / 389

Let's proceed to step 4:
If we divide 359 by 389, we get 0 and a remainder of 359.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 359 after subtracting 0 from 359.
Bring next digit (9) of the dividend behind the 359 and repeat the process: 3599 / 389

Moving on to step 5:
If we divide 3599 by 389, we get 9 and a remainder of 98.
Record the quotient 9 as the next digit in the result. 
Result so far: 209.0
If we take 3501 away from 3599, we end up with 98.
Append the next digit (5) from the dividend to 98 and continue with: 985 / 389

Let's proceed to step 6:
389 can be fit into 985 2 times, resulting in a remainder of 207.
Write down 2 as next digit of the result. 
Result so far: 2092.0
If we subtract 778 from 985, we get 207.
Bring next digit (6) of the dividend behind the 207 and repeat the process: 2076 / 389

Step 7:
If we divide 2076 by 389, we get 5 and a remainder of 131.
Record the quotient 5 as the next digit in the result. 
Result so far: 20925.0
Subtract 1945 from 2076 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 8:
389 goes into 1310 3 times with a remainder of 143.
Use 3 as the next digit of our solution. 
Result so far: 20925.3
If we take 1167 away from 1310, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 9:
389 can be fit into 1430 3 times, resulting in a remainder of 263.
Write down 3 as next digit of the result. 
Result so far: 20925.33
Subtract 1167 from 1430 to get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

The final result is 20925.33 with a remainder of 0.263.
