Let's divide 66549044 by 438
We want to divide 66549044 by 438.

Advancing to step 1:
The number 438 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 438

Moving on to step 2:
The number 438 fits into 66 0 times, leaving a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (5) from the dividend, attach it to 66 and continue: 665 / 438

Advancing to step 3:
438 can be fit into 665 1 times, resulting in a remainder of 227.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 438 from 665, we get 227.
Take the next digit (4) from the dividend and append it to 227, then repeat: 2274 / 438

Step 4:
When dividing 2274 by 438, we get 5 with a remainder of 84.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 2190 from 2274 leaves us with 84.
Grab the next digit (9) from the dividend, add it to 84, then carry on: 849 / 438

Advancing to step 5:
If we divide 849 by 438, we get 1 and a remainder of 411.
Write down 1 as next digit of the result. 
Result so far: 151.0
If we subtract 438 from 849, we get 411.
Include the next digit (0) from the dividend after 411, then repeat: 4110 / 438

On to step 6:
The number 438 fits into 4110 9 times, leaving a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 1519.0
Deduct 3942 from 4110 and we're left with 168.
Include the next digit (4) from the dividend after 168, then repeat: 1684 / 438

Moving on to step 7:
438 goes into 1684 3 times with a remainder of 370.
The next digit of our result is 3. 
Result so far: 15193.0
If we subtract 1314 from 1684, we get 370.
Take the next digit (4) from the dividend and append it to 370, then repeat: 3704 / 438

Step 8:
When dividing 3704 by 438, we get 8 with a remainder of 200.
The number 8 becomes the next digit in our result. 
Result so far: 151938.0
If we take 3504 away from 3704, we end up 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.

Step 9:
If we divide 2000 by 438, we get 4 and a remainder of 248.
Record the quotient 4 as the next digit in the result. 
Result so far: 151938.4
If we subtract 1752 from 2000, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 10:
438 can be fit into 2480 5 times, resulting in a remainder of 290.
The number 5 becomes the next digit in our result. 
Result so far: 151938.45
If we subtract 2190 from 2480, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 11:
If we divide 2900 by 438, we get 6 and a remainder of 272.
The next digit of our result is 6. 
Result so far: 151938.456
Subtracting 2628 from 2900 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 12:
438 can be fit into 2720 6 times, resulting in a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 151938.4566
If we subtract 2628 from 2720, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Our division results in 151938.4566 with a remaining 0.00092.
