638098 divided by 39 
Our goal is to divide 638098 by 39.

On to step 1:
6 divided by 39 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 39

Let's proceed to step 2:
39 goes into 63 1 times with a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 39 from 63 leaves us with 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 39

Going ahead to step 3:
39 can be fit into 248 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 234 from 248 leaves us with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 39

Step 4:
140 divided by 39 is 3 with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 163.0
The remainder is 23 after subtracting 117 from 140.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 39

Going ahead to step 5:
39 can be fit into 239 6 times, resulting in a remainder of 5.
The next digit of our result is 6. 
Result so far: 1636.0
Subtracting 234 from 239 leaves us with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 39

Step 6:
The number 39 fits into 58 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 16361.0
If we take 39 away from 58, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
The number 39 fits into 190 4 times, leaving a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 16361.4
Subtracting 156 from 190 leaves us 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.

On to step 8:
340 divided by 39 is 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 16361.48
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
If we divide 280 by 39, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 16361.487
If we subtract 273 from 280, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
70 divided by 39 is 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 16361.4871
Subtracting 39 from 70 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 11:
310 divided by 39 is 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 16361.48717
The remainder is 37 after subtracting 273 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 12:
The number 39 fits into 370 9 times, leaving a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 16361.487179
If we subtract 351 from 370, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 13:
39 can be fit into 190 4 times, resulting in a remainder of 34.
The next digit of our result is 4. 
Result so far: 16361.4871794
Subtract 156 from 190 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 14:
When dividing 340 by 39, we get 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 16361.48717948
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 16361.48717948 and a remainder of 2.8e-08.
