We look at the division of 39370206 by 231 
We want to figure out the number of times 39370206 can be divided by 231.

Moving on to step 1:
231 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 231

Going ahead to step 2:
39 divided by 231 is 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 231

Advancing to step 3:
The number 231 fits into 393 1 times, leaving a remainder of 162.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 231 from 393 leaves us with 162.
Grab the next digit (7) from the dividend, add it to 162, then carry on: 1627 / 231

On to step 4:
231 can be fit into 1627 7 times, resulting in a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 1617 from 1627 leaves us with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 231

Advancing to step 5:
231 can be fit into 100 0 times, resulting in a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 170.0
If we take 0 away from 100, we end up with 100.
Include the next digit (2) from the dividend after 100, then repeat: 1002 / 231

Advancing to step 6:
When dividing 1002 by 231, we get 4 with a remainder of 78.
Put 4 as the next digit of the answer. 
Result so far: 1704.0
The remainder is 78 after subtracting 924 from 1002.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 231

Step 7:
231 can be fit into 780 3 times, resulting in a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 17043.0
The remainder is 87 after subtracting 693 from 780.
Take the next digit (6) from the dividend and append it to 87, then repeat: 876 / 231

On to step 8:
876 divided by 231 is 3 with a remainder of 183.
Record the quotient 3 as the next digit in the result. 
Result so far: 170433.0
Subtract 693 from 876 to get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Advancing to step 9:
When dividing 1830 by 231, we get 7 with a remainder of 213.
Use 7 as the next digit of our solution. 
Result so far: 170433.7
Subtract 1617 from 1830 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Let's proceed to step 10:
2130 divided by 231 is 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 170433.79
The remainder is 51 after subtracting 2079 from 2130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 11:
231 goes into 510 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 170433.792
Subtracting 462 from 510 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
When dividing 480 by 231, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 170433.7922
Deduct 462 from 480 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 170433.7922 and a remainder of 0.00018.
