39378937 ÷ 207 
We're looking to find how many times 207 goes into 39378937.

Moving on to step 1:
207 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 207

Step 2:
When dividing 39 by 207, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 207

Going ahead to step 3:
If we divide 393 by 207, we get 1 and a remainder of 186.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 207 from 393, we get 186.
Append the next digit (7) from the dividend to 186 and continue with: 1867 / 207

Going ahead to step 4:
1867 divided by 207 is 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 1863 from 1867, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 207

On to step 5:
207 goes into 48 0 times with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 190.0
Subtract 0 from 48 to get 48.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 207

On to step 6:
207 goes into 489 2 times with a remainder of 75.
The number 2 becomes the next digit in our result. 
Result so far: 1902.0
If we take 414 away from 489, we end up with 75.
Fetch the next digit (3) from the dividend, attach it to 75 and continue: 753 / 207

Advancing to step 7:
If we divide 753 by 207, we get 3 and a remainder of 132.
The next digit of our result is 3. 
Result so far: 19023.0
Deduct 621 from 753 and we're left with 132.
Take the next digit (7) from the dividend and append it to 132, then repeat: 1327 / 207

On to step 8:
207 can be fit into 1327 6 times, resulting in a remainder of 85.
Use 6 as the next digit of our solution. 
Result so far: 190236.0
Subtracting 1242 from 1327 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 9:
207 goes into 850 4 times with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 190236.4
Subtracting 828 from 850 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
207 goes into 220 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 190236.41
Subtracting 207 from 220 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 11:
When dividing 130 by 207, we get 0 with a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 190236.41
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 12:
If we divide 1300 by 207, we get 6 and a remainder of 58.
The next digit of our result is 6. 
Result so far: 190236.4106
Subtract 1242 from 1300 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
When dividing 580 by 207, we get 2 with a remainder of 166.
Put 2 as the next digit of the answer. 
Result so far: 190236.41062
Deduct 414 from 580 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 14:
207 goes into 1660 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 190236.410628
If we take 1656 away from 1660, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 15:
40 divided by 207 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 190236.410628
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 16:
The number 207 fits into 400 1 times, leaving a remainder of 193.
Put 1 as the next digit of the answer. 
Result so far: 190236.41062801
Subtract 207 from 400 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

After the division, we end up with 190236.41062801 and a remainder of 1.93e-07.
