343381 divided by 73 
The aim is to understand the frequency of 73 in 343381.

On to step 1:
73 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 73

Let's proceed to step 2:
When dividing 34 by 73, we get 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 73

Let's proceed to step 3:
When dividing 343 by 73, we get 4 with a remainder of 51.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 292 from 343 and we're left with 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 73

Step 4:
73 can be fit into 513 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Deduct 511 from 513 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 73

Step 5:
73 can be fit into 28 0 times, resulting in a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 470.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 73

Moving on to step 6:
The number 73 fits into 281 3 times, leaving a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 4703.0
The remainder is 62 after subtracting 219 from 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 7:
When dividing 620 by 73, we get 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 4703.8
Subtracting 584 from 620 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
The number 73 fits into 360 4 times, leaving a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 4703.84
The remainder is 68 after subtracting 292 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
73 goes into 680 9 times with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 4703.849
Deduct 657 from 680 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
The number 73 fits into 230 3 times, leaving a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 4703.8493
Subtract 219 from 230 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
If we divide 110 by 73, we get 1 and a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 4703.84931
The remainder is 37 after subtracting 73 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
73 can be fit into 370 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 4703.849315
If we subtract 365 from 370, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
73 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 4703.849315
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
500 divided by 73 is 6 with a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 4703.84931506
If we take 438 away from 500, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 4703.84931506 and a remainder of 6.2e-08.
