We look at the division of 139078 by 35 
We're looking to find how many times 35 goes into 139078.

Let's proceed to step 1:
35 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 35

Let's proceed to step 2:
When dividing 13 by 35, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 35

Moving on to step 3:
35 can be fit into 139 3 times, resulting in a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 105 from 139 to get 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 35

Let's proceed to step 4:
When dividing 340 by 35, we get 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtracting 315 from 340 leaves us with 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 35

Advancing to step 5:
35 can be fit into 257 7 times, resulting in a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 397.0
The remainder is 12 after subtracting 245 from 257.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 35

On to step 6:
35 goes into 128 3 times with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 3973.0
The remainder is 23 after subtracting 105 from 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
230 divided by 35 is 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 3973.6
Subtract 210 from 230 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
200 divided by 35 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 3973.65
Deduct 175 from 200 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
When dividing 250 by 35, we get 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 3973.657
Deduct 245 from 250 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.

Let's proceed to step 10:
If we divide 50 by 35, we get 1 and a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 3973.6571
If we subtract 35 from 50, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
150 divided by 35 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 3973.65714
If we take 140 away from 150, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
If we divide 100 by 35, we get 2 and a remainder of 30.
The next digit of our result is 2. 
Result so far: 3973.657142
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
35 goes into 300 8 times with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 3973.6571428
Deduct 280 from 300 and we're left 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.

Let's proceed to step 14:
35 goes into 200 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 3973.65714285
If we subtract 175 from 200, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 3973.65714285, with a leftover of 2.5e-08.
