125207 ÷ 39 
We're looking to find how many times 39 goes into 125207.

On to step 1:
The number 39 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 39

Step 2:
39 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 39

Step 3:
39 can be fit into 125 3 times, resulting in a remainder of 8.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 117 from 125 leaves us with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 39

Going ahead to step 4:
39 can be fit into 82 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Deduct 78 from 82 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 39

Advancing to step 5:
The number 39 fits into 40 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 321.0
Deduct 39 from 40 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 39

Moving on to step 6:
The number 39 fits into 17 0 times, leaving a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 3210.0
If we take 0 away from 17, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
The number 39 fits into 170 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 3210.4
Subtracting 156 from 170 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
The number 39 fits into 140 3 times, leaving a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 3210.43
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 9:
39 goes into 230 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 3210.435
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.

Step 10:
39 goes into 350 8 times with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 3210.4358
If we subtract 312 from 350, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
39 can be fit into 380 9 times, resulting in a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 3210.43589
Subtracting 351 from 380 leaves us 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.

On to step 12:
290 divided by 39 is 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 3210.435897
Subtracting 273 from 290 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 13:
When dividing 170 by 39, we get 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 3210.4358974
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.

Step 14:
140 divided by 39 is 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 3210.43589743
The remainder is 23 after subtracting 117 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The quotient of the division is 3210.43589743, and the remainder is 2.3e-08.
