45778372 ÷ 438 
Let's see how many times 438 fits into 45778372.

On to step 1:
If we divide 4 by 438, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 438

On to step 2:
438 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 438

Moving on to step 3:
When dividing 457 by 438, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 438 from 457 leaves us with 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 438

Going ahead to step 4:
When dividing 197 by 438, we get 0 with a remainder of 197.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 197 and we're left with 197.
Bring next digit (8) of the dividend behind the 197 and repeat the process: 1978 / 438

Advancing to step 5:
438 can be fit into 1978 4 times, resulting in a remainder of 226.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
If we subtract 1752 from 1978, we get 226.
Take the next digit (3) from the dividend and append it to 226, then repeat: 2263 / 438

Going ahead to step 6:
If we divide 2263 by 438, we get 5 and a remainder of 73.
Record the quotient 5 as the next digit in the result. 
Result so far: 1045.0
Subtracting 2190 from 2263 leaves us with 73.
Bring next digit (7) of the dividend behind the 73 and repeat the process: 737 / 438

On to step 7:
438 goes into 737 1 times with a remainder of 299.
The number 1 becomes the next digit in our result. 
Result so far: 10451.0
Subtract 438 from 737 to get 299.
Include the next digit (2) from the dividend after 299, then repeat: 2992 / 438

Let's proceed to step 8:
When dividing 2992 by 438, we get 6 with a remainder of 364.
The next digit of our result is 6. 
Result so far: 104516.0
Subtracting 2628 from 2992 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 9:
3640 divided by 438 is 8 with a remainder of 136.
Use 8 as the next digit of our solution. 
Result so far: 104516.8
If we take 3504 away from 3640, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 10:
If we divide 1360 by 438, we get 3 and a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 104516.83
Subtracting 1314 from 1360 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 11:
460 divided by 438 is 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 104516.831
If we take 438 away from 460, we end up 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.

Moving on to step 12:
438 goes into 220 0 times with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 104516.831
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 13:
438 can be fit into 2200 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 104516.83105
If we take 2190 away from 2200, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
The number 438 fits into 100 0 times, leaving a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 104516.83105
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 15:
1000 divided by 438 is 2 with a remainder of 124.
The number 2 becomes the next digit in our result. 
Result so far: 104516.8310502
Deduct 876 from 1000 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 16:
If we divide 1240 by 438, we get 2 and a remainder of 364.
Record the quotient 2 as the next digit in the result. 
Result so far: 104516.83105022
Deduct 876 from 1240 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

The final result is 104516.83105022 with a remainder of 3.64e-07.
