3361234 divided by 336 
The aim is to understand the frequency of 336 in 3361234.

On to step 1:
336 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 336

Going ahead to step 2:
336 can be fit into 33 0 times, resulting in a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 336

Advancing to step 3:
336 divided by 336 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 336 from 336 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 336

Moving on to step 4:
When dividing 1 by 336, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 336

On to step 5:
If we divide 12 by 336, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 336

Moving on to step 6:
336 goes into 123 0 times with a remainder of 123.
The next digit of our result is 0. 
Result so far: 1000.0
If we subtract 0 from 123, we get 123.
Grab the next digit (4) from the dividend, add it to 123, then carry on: 1234 / 336

Step 7:
336 goes into 1234 3 times with a remainder of 226.
Use 3 as the next digit of our solution. 
Result so far: 10003.0
Subtracting 1008 from 1234 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 8:
When dividing 2260 by 336, we get 6 with a remainder of 244.
Put 6 as the next digit of the answer. 
Result so far: 10003.6
Subtracting 2016 from 2260 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 9:
2440 divided by 336 is 7 with a remainder of 88.
Record the quotient 7 as the next digit in the result. 
Result so far: 10003.67
Subtract 2352 from 2440 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 10:
880 divided by 336 is 2 with a remainder of 208.
Put 2 as the next digit of the answer. 
Result so far: 10003.672
If we take 672 away from 880, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 11:
336 goes into 2080 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 10003.6726
Subtracting 2016 from 2080 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
When dividing 640 by 336, we get 1 with a remainder of 304.
Record the quotient 1 as the next digit in the result. 
Result so far: 10003.67261
Deduct 336 from 640 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 13:
If we divide 3040 by 336, we get 9 and a remainder of 16.
The next digit of our result is 9. 
Result so far: 10003.672619
Subtract 3024 from 3040 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
336 goes into 160 0 times with a remainder of 160.
The next digit of our result is 0. 
Result so far: 10003.672619
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 15:
336 goes into 1600 4 times with a remainder of 256.
The next digit of our result is 4. 
Result so far: 10003.67261904
If we subtract 1344 from 1600, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final outcome is 10003.67261904, with a leftover of 2.56e-07.
