16439488 divided by 438 
We want to divide 16439488 by 438.

Moving on to step 1:
When dividing 1 by 438, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 438

Advancing to step 2:
438 can be fit into 16 0 times, resulting in a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 438

Advancing to step 3:
If we divide 164 by 438, we get 0 and a remainder of 164.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 164, we get 164.
Fetch the next digit (3) from the dividend, attach it to 164 and continue: 1643 / 438

Let's proceed to step 4:
438 goes into 1643 3 times with a remainder of 329.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 1314 from 1643 leaves us with 329.
Take the next digit (9) from the dividend and append it to 329, then repeat: 3299 / 438

Step 5:
The number 438 fits into 3299 7 times, leaving a remainder of 233.
Write down 7 as next digit of the result. 
Result so far: 37.0
If we subtract 3066 from 3299, we get 233.
Grab the next digit (4) from the dividend, add it to 233, then carry on: 2334 / 438

Advancing to step 6:
438 can be fit into 2334 5 times, resulting in a remainder of 144.
Record the quotient 5 as the next digit in the result. 
Result so far: 375.0
If we subtract 2190 from 2334, we get 144.
Include the next digit (8) from the dividend after 144, then repeat: 1448 / 438

On to step 7:
If we divide 1448 by 438, we get 3 and a remainder of 134.
Use 3 as the next digit of our solution. 
Result so far: 3753.0
Deduct 1314 from 1448 and we're left with 134.
Fetch the next digit (8) from the dividend, attach it to 134 and continue: 1348 / 438

Advancing to step 8:
438 can be fit into 1348 3 times, resulting in a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 37533.0
Deduct 1314 from 1348 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.

Going ahead to step 9:
438 can be fit into 340 0 times, resulting in a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 37533.0
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 10:
438 goes into 3400 7 times with a remainder of 334.
Use 7 as the next digit of our solution. 
Result so far: 37533.07
The remainder is 334 after subtracting 3066 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Moving on to step 11:
If we divide 3340 by 438, we get 7 and a remainder of 274.
Write down 7 as next digit of the result. 
Result so far: 37533.077
If we subtract 3066 from 3340, we 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.

Our division results in 37533.077 with a remaining 0.0274.
