Let's divide 278225 by 39
We're looking to find how many times 39 goes into 278225.

Advancing to step 1:
2 divided by 39 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 39

Going ahead to step 2:
39 can be fit into 27 0 times, resulting in a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 39

Going ahead to step 3:
278 divided by 39 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 273 away from 278, we end up with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 39

Let's proceed to step 4:
If we divide 52 by 39, we get 1 and a remainder of 13.
The next digit of our result is 1. 
Result so far: 71.0
The remainder is 13 after subtracting 39 from 52.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 39

Advancing to step 5:
132 divided by 39 is 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 713.0
If we subtract 117 from 132, we get 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 39

Let's proceed to step 6:
39 goes into 155 3 times with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 7133.0
Deduct 117 from 155 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
The number 39 fits into 380 9 times, leaving a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 7133.9
If we take 351 away from 380, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 8:
If we divide 290 by 39, we get 7 and a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 7133.97
Subtract 273 from 290 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
39 can be fit into 170 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 7133.974
If we subtract 156 from 170, we get 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 10:
140 divided by 39 is 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 7133.9743
If we take 117 away from 140, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 11:
39 goes into 230 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 7133.97435
If we subtract 195 from 230, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 12:
350 divided by 39 is 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 7133.974358
Subtracting 312 from 350 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
If we divide 380 by 39, we get 9 and a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 7133.9743589
If we take 351 away from 380, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 14:
39 goes into 290 7 times with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 7133.97435897
The remainder is 17 after subtracting 273 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 7133.97435897, with a leftover of 1.7e-08.
