We're dividing 66494119 by 438 
We want to divide 66494119 by 438.

Moving on to step 1:
438 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 438

Going ahead to step 2:
If we divide 66 by 438, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 438

Let's proceed to step 3:
664 divided by 438 is 1 with a remainder of 226.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 438 from 664 to get 226.
Append the next digit (9) from the dividend to 226 and continue with: 2269 / 438

Moving on to step 4:
The number 438 fits into 2269 5 times, leaving a remainder of 79.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 2190 from 2269, we get 79.
Bring next digit (4) of the dividend behind the 79 and repeat the process: 794 / 438

Let's proceed to step 5:
438 goes into 794 1 times with a remainder of 356.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
If we subtract 438 from 794, we get 356.
Take the next digit (1) from the dividend and append it to 356, then repeat: 3561 / 438

Let's proceed to step 6:
3561 divided by 438 is 8 with a remainder of 57.
Write down 8 as next digit of the result. 
Result so far: 1518.0
The remainder is 57 after subtracting 3504 from 3561.
Include the next digit (1) from the dividend after 57, then repeat: 571 / 438

Advancing to step 7:
When dividing 571 by 438, we get 1 with a remainder of 133.
The next digit of our result is 1. 
Result so far: 15181.0
Subtracting 438 from 571 leaves us with 133.
Bring next digit (9) of the dividend behind the 133 and repeat the process: 1339 / 438

Advancing to step 8:
438 goes into 1339 3 times with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 151813.0
Deduct 1314 from 1339 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 9:
The number 438 fits into 250 0 times, leaving a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 151813.0
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 10:
The number 438 fits into 2500 5 times, leaving a remainder of 310.
Put 5 as the next digit of the answer. 
Result so far: 151813.05
If we subtract 2190 from 2500, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 11:
438 goes into 3100 7 times with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 151813.057
Deduct 3066 from 3100 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 12:
When dividing 340 by 438, we get 0 with a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 151813.057
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 13:
438 can be fit into 3400 7 times, resulting in a remainder of 334.
The next digit of our result is 7. 
Result so far: 151813.05707
Subtract 3066 from 3400 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 14:
If we divide 3340 by 438, we get 7 and a remainder of 274.
Put 7 as the next digit of the answer. 
Result so far: 151813.057077
Subtract 3066 from 3340 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

In conclusion, the division gives 151813.057077 with a balance of 2.74e-05.
