We divide 42815 by 39
Our goal is to divide 42815 by 39.

Advancing to step 1:
When dividing 4 by 39, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 39

Advancing to step 2:
39 goes into 42 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 39 from 42 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 39

Going ahead to step 3:
38 divided by 39 is 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 38 and we're left with 38.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 39

Advancing to step 4:
If we divide 381 by 39, we get 9 and a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 109.0
Subtracting 351 from 381 leaves us with 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 39

Step 5:
305 divided by 39 is 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 1097.0
If we take 273 away from 305, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 6:
The number 39 fits into 320 8 times, leaving a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 1097.8
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
80 divided by 39 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 1097.82
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
If we divide 20 by 39, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1097.82
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
The number 39 fits into 200 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 1097.8205
Deduct 195 from 200 and we're left with 5.
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 10:
39 can be fit into 50 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1097.82051
If we take 39 away from 50, we end up 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.

Moving on to step 11:
39 goes into 110 2 times with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 1097.820512
Subtract 78 from 110 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
When dividing 320 by 39, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 1097.8205128
Subtracting 312 from 320 leaves us 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 13:
If we divide 80 by 39, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 1097.82051282
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 1097.82051282 with a remainder of 2e-09.
