51609344 ÷ 338 
The aim is to understand the frequency of 338 in 51609344.

On to step 1:
The number 338 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 338

Step 2:
51 divided by 338 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Take the next digit (6) from the dividend and append it to 51, then repeat: 516 / 338

Advancing to step 3:
338 goes into 516 1 times with a remainder of 178.
The next digit of our result is 1. 
Result so far: 1.0
If we take 338 away from 516, we end up with 178.
Grab the next digit (0) from the dividend, add it to 178, then carry on: 1780 / 338

On to step 4:
If we divide 1780 by 338, we get 5 and a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 1690 away from 1780, we end up with 90.
Bring next digit (9) of the dividend behind the 90 and repeat the process: 909 / 338

Going ahead to step 5:
If we divide 909 by 338, we get 2 and a remainder of 233.
The next digit of our result is 2. 
Result so far: 152.0
Subtracting 676 from 909 leaves us with 233.
Fetch the next digit (3) from the dividend, attach it to 233 and continue: 2333 / 338

Advancing to step 6:
If we divide 2333 by 338, we get 6 and a remainder of 305.
Write down 6 as next digit of the result. 
Result so far: 1526.0
Subtracting 2028 from 2333 leaves us with 305.
Grab the next digit (4) from the dividend, add it to 305, then carry on: 3054 / 338

Going ahead to step 7:
The number 338 fits into 3054 9 times, leaving a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 15269.0
If we subtract 3042 from 3054, we get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 338

Going ahead to step 8:
338 can be fit into 124 0 times, resulting in a remainder of 124.
Write down 0 as next digit of the result. 
Result so far: 152690.0
Deduct 0 from 124 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 9:
If we divide 1240 by 338, we get 3 and a remainder of 226.
Record the quotient 3 as the next digit in the result. 
Result so far: 152690.3
If we subtract 1014 from 1240, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 10:
The number 338 fits into 2260 6 times, leaving a remainder of 232.
The number 6 becomes the next digit in our result. 
Result so far: 152690.36
Subtract 2028 from 2260 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 11:
When dividing 2320 by 338, we get 6 with a remainder of 292.
The number 6 becomes the next digit in our result. 
Result so far: 152690.366
If we take 2028 away from 2320, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

After the division, we end up with 152690.366 and a remainder of 0.0292.
