We divide 639848 by 38
The aim is to understand the frequency of 38 in 639848.

On to step 1:
When dividing 6 by 38, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 38

Step 2:
If we divide 63 by 38, we get 1 and a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 38 away from 63, we end up with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 38

Advancing to step 3:
38 goes into 259 6 times with a remainder of 31.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 228 from 259 leaves us with 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 38

Step 4:
The number 38 fits into 318 8 times, leaving a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
If we take 304 away from 318, we end up with 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 38

Let's proceed to step 5:
The number 38 fits into 144 3 times, leaving a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 1683.0
Subtracting 114 from 144 leaves us with 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 38

Advancing to step 6:
If we divide 308 by 38, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 16838.0
Subtracting 304 from 308 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
If we divide 40 by 38, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 16838.1
Subtracting 38 from 40 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
The number 38 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 16838.1
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
38 goes into 200 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 16838.105
Subtracting 190 from 200 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
The number 38 fits into 100 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 16838.1052
If we subtract 76 from 100, we 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 11:
The number 38 fits into 240 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 16838.10526
Deduct 228 from 240 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
120 divided by 38 is 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 16838.105263
Deduct 114 from 120 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
60 divided by 38 is 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 16838.1052631
The remainder is 22 after subtracting 38 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 14:
If we divide 220 by 38, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 16838.10526315
Deduct 190 from 220 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 16838.10526315 and a remainder of 3e-08.
