63839360 ÷ 207 
Let's see how many times 207 fits into 63839360.

On to step 1:
207 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 207

Step 2:
63 divided by 207 is 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Grab the next digit (8) from the dividend, add it to 63, then carry on: 638 / 207

Let's proceed to step 3:
When dividing 638 by 207, we get 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 621 from 638 and we're left with 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 207

Going ahead to step 4:
207 goes into 173 0 times with a remainder of 173.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we subtract 0 from 173, we get 173.
Append the next digit (9) from the dividend to 173 and continue with: 1739 / 207

On to step 5:
207 goes into 1739 8 times with a remainder of 83.
Record the quotient 8 as the next digit in the result. 
Result so far: 308.0
Subtract 1656 from 1739 to get 83.
Take the next digit (3) from the dividend and append it to 83, then repeat: 833 / 207

Let's proceed to step 6:
If we divide 833 by 207, we get 4 and a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 3084.0
If we take 828 away from 833, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 207

Step 7:
If we divide 56 by 207, we get 0 and a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 30840.0
If we take 0 away from 56, we end up with 56.
Bring next digit (0) of the dividend behind the 56 and repeat the process: 560 / 207

Let's proceed to step 8:
560 divided by 207 is 2 with a remainder of 146.
The next digit of our result is 2. 
Result so far: 308402.0
Deduct 414 from 560 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 9:
1460 divided by 207 is 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 308402.7
If we subtract 1449 from 1460, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 10:
When dividing 110 by 207, we get 0 with a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 308402.7
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 11:
When dividing 1100 by 207, we get 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 308402.705
If we take 1035 away from 1100, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 12:
207 can be fit into 650 3 times, resulting in a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 308402.7053
If we subtract 621 from 650, we get 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 13:
290 divided by 207 is 1 with a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 308402.70531
If we subtract 207 from 290, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 14:
207 goes into 830 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 308402.705314
If we subtract 828 from 830, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 15:
The number 207 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 308402.705314
If we subtract 0 from 20, we 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.

Advancing to step 16:
200 divided by 207 is 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 308402.705314
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 308402.705314 with a balance of 2e-07.
