We divide 63945400 by 438
We're looking to find how many times 438 goes into 63945400.

Advancing to step 1:
If we divide 6 by 438, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 438

Moving on to step 2:
438 can be fit into 63 0 times, resulting in a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 438

On to step 3:
639 divided by 438 is 1 with a remainder of 201.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 438 from 639 to get 201.
Append the next digit (4) from the dividend to 201 and continue with: 2014 / 438

Let's proceed to step 4:
When dividing 2014 by 438, we get 4 with a remainder of 262.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 1752 from 2014 to get 262.
Take the next digit (5) from the dividend and append it to 262, then repeat: 2625 / 438

Step 5:
438 can be fit into 2625 5 times, resulting in a remainder of 435.
Write down 5 as next digit of the result. 
Result so far: 145.0
If we take 2190 away from 2625, we end up with 435.
Fetch the next digit (4) from the dividend, attach it to 435 and continue: 4354 / 438

Advancing to step 6:
If we divide 4354 by 438, we get 9 and a remainder of 412.
The next digit of our result is 9. 
Result so far: 1459.0
Subtracting 3942 from 4354 leaves us with 412.
Include the next digit (0) from the dividend after 412, then repeat: 4120 / 438

Let's proceed to step 7:
If we divide 4120 by 438, we get 9 and a remainder of 178.
Put 9 as the next digit of the answer. 
Result so far: 14599.0
If we subtract 3942 from 4120, we get 178.
Include the next digit (0) from the dividend after 178, then repeat: 1780 / 438

On to step 8:
The number 438 fits into 1780 4 times, leaving a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 145994.0
Deduct 1752 from 1780 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
280 divided by 438 is 0 with a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 145994.0
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 10:
438 goes into 2800 6 times with a remainder of 172.
Write down 6 as next digit of the result. 
Result so far: 145994.06
Subtract 2628 from 2800 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 11:
438 can be fit into 1720 3 times, resulting in a remainder of 406.
Record the quotient 3 as the next digit in the result. 
Result so far: 145994.063
Subtract 1314 from 1720 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 12:
When dividing 4060 by 438, we get 9 with a remainder of 118.
The number 9 becomes the next digit in our result. 
Result so far: 145994.0639
Subtracting 3942 from 4060 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 13:
When dividing 1180 by 438, we get 2 with a remainder of 304.
The number 2 becomes the next digit in our result. 
Result so far: 145994.06392
If we subtract 876 from 1180, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 14:
438 can be fit into 3040 6 times, resulting in a remainder of 412.
Write down 6 as next digit of the result. 
Result so far: 145994.063926
Deduct 2628 from 3040 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 15:
438 goes into 4120 9 times with a remainder of 178.
The number 9 becomes the next digit in our result. 
Result so far: 145994.0639269
Subtract 3942 from 4120 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 16:
The number 438 fits into 1780 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 145994.06392694
Subtracting 1752 from 1780 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 145994.06392694, with a leftover of 2.8e-08.
