Let's divide 13998939 by 438
We want to divide 13998939 by 438.

Step 1:
If we divide 1 by 438, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 438

Advancing to step 2:
If we divide 13 by 438, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 438

Step 3:
438 can be fit into 139 0 times, resulting in a remainder of 139.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 139, we end up with 139.
Grab the next digit (9) from the dividend, add it to 139, then carry on: 1399 / 438

Let's proceed to step 4:
438 can be fit into 1399 3 times, resulting in a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 1314 away from 1399, we end up with 85.
Take the next digit (8) from the dividend and append it to 85, then repeat: 858 / 438

Advancing to step 5:
If we divide 858 by 438, we get 1 and a remainder of 420.
Write down 1 as next digit of the result. 
Result so far: 31.0
Deduct 438 from 858 and we're left with 420.
Take the next digit (9) from the dividend and append it to 420, then repeat: 4209 / 438

Going ahead to step 6:
When dividing 4209 by 438, we get 9 with a remainder of 267.
The next digit of our result is 9. 
Result so far: 319.0
Deduct 3942 from 4209 and we're left with 267.
Fetch the next digit (3) from the dividend, attach it to 267 and continue: 2673 / 438

Moving on to step 7:
If we divide 2673 by 438, we get 6 and a remainder of 45.
Use 6 as the next digit of our solution. 
Result so far: 3196.0
Subtracting 2628 from 2673 leaves us with 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 438

Let's proceed to step 8:
If we divide 459 by 438, we get 1 and a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 31961.0
If we subtract 438 from 459, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
If we divide 210 by 438, we get 0 and a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 31961.0
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 10:
The number 438 fits into 2100 4 times, leaving a remainder of 348.
Use 4 as the next digit of our solution. 
Result so far: 31961.04
Subtract 1752 from 2100 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 11:
438 goes into 3480 7 times with a remainder of 414.
Write down 7 as next digit of the result. 
Result so far: 31961.047
Deduct 3066 from 3480 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 12:
If we divide 4140 by 438, we get 9 and a remainder of 198.
Record the quotient 9 as the next digit in the result. 
Result so far: 31961.0479
If we take 3942 away from 4140, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 13:
438 goes into 1980 4 times with a remainder of 228.
Record the quotient 4 as the next digit in the result. 
Result so far: 31961.04794
Subtract 1752 from 1980 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 14:
If we divide 2280 by 438, we get 5 and a remainder of 90.
The next digit of our result is 5. 
Result so far: 31961.047945
If we take 2190 away from 2280, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 15:
900 divided by 438 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 31961.0479452
Subtract 876 from 900 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 16:
438 goes into 240 0 times with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 31961.0479452
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 31961.0479452 with a remainder of 2.4e-07.
