43513424 ÷ 438 
We're looking to find how many times 438 goes into 43513424.

On to step 1:
If we divide 4 by 438, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 438

Moving on to step 2:
When dividing 43 by 438, we get 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 438

On to step 3:
438 goes into 435 0 times with a remainder of 435.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 435, we get 435.
Include the next digit (1) from the dividend after 435, then repeat: 4351 / 438

Let's proceed to step 4:
If we divide 4351 by 438, we get 9 and a remainder of 409.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 3942 from 4351 leaves us with 409.
Fetch the next digit (3) from the dividend, attach it to 409 and continue: 4093 / 438

Moving on to step 5:
4093 divided by 438 is 9 with a remainder of 151.
The next digit of our result is 9. 
Result so far: 99.0
Subtract 3942 from 4093 to get 151.
Take the next digit (4) from the dividend and append it to 151, then repeat: 1514 / 438

Moving on to step 6:
438 can be fit into 1514 3 times, resulting in a remainder of 200.
The number 3 becomes the next digit in our result. 
Result so far: 993.0
Subtract 1314 from 1514 to get 200.
Take the next digit (2) from the dividend and append it to 200, then repeat: 2002 / 438

Step 7:
If we divide 2002 by 438, we get 4 and a remainder of 250.
The number 4 becomes the next digit in our result. 
Result so far: 9934.0
If we take 1752 away from 2002, we end up with 250.
Bring next digit (4) of the dividend behind the 250 and repeat the process: 2504 / 438

Step 8:
If we divide 2504 by 438, we get 5 and a remainder of 314.
Record the quotient 5 as the next digit in the result. 
Result so far: 99345.0
If we subtract 2190 from 2504, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 9:
If we divide 3140 by 438, we get 7 and a remainder of 74.
The next digit of our result is 7. 
Result so far: 99345.7
Deduct 3066 from 3140 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 10:
438 can be fit into 740 1 times, resulting in a remainder of 302.
Put 1 as the next digit of the answer. 
Result so far: 99345.71
If we subtract 438 from 740, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 11:
When dividing 3020 by 438, we get 6 with a remainder of 392.
The next digit of our result is 6. 
Result so far: 99345.716
If we take 2628 away from 3020, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 12:
When dividing 3920 by 438, we get 8 with a remainder of 416.
Put 8 as the next digit of the answer. 
Result so far: 99345.7168
Subtracting 3504 from 3920 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 13:
4160 divided by 438 is 9 with a remainder of 218.
The number 9 becomes the next digit in our result. 
Result so far: 99345.71689
The remainder is 218 after subtracting 3942 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 14:
438 can be fit into 2180 4 times, resulting in a remainder of 428.
The next digit of our result is 4. 
Result so far: 99345.716894
The remainder is 428 after subtracting 1752 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Let's proceed to step 15:
If we divide 4280 by 438, we get 9 and a remainder of 338.
Record the quotient 9 as the next digit in the result. 
Result so far: 99345.7168949
Subtracting 3942 from 4280 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 16:
3380 divided by 438 is 7 with a remainder of 314.
Use 7 as the next digit of our solution. 
Result so far: 99345.71689497
If we subtract 3066 from 3380, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

The quotient of the division is 99345.71689497, and the remainder is 3.14e-07.
