We divide 43507793 by 354
The aim is to understand the frequency of 354 in 43507793.

Advancing to step 1:
When dividing 4 by 354, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 354

Advancing to step 2:
When dividing 43 by 354, we get 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 354

Step 3:
354 goes into 435 1 times with a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 354 from 435 to get 81.
Append the next digit (0) from the dividend to 81 and continue with: 810 / 354

Let's proceed to step 4:
354 goes into 810 2 times with a remainder of 102.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 708 from 810 leaves us with 102.
Take the next digit (7) from the dividend and append it to 102, then repeat: 1027 / 354

On to step 5:
354 goes into 1027 2 times with a remainder of 319.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Subtracting 708 from 1027 leaves us with 319.
Append the next digit (7) from the dividend to 319 and continue with: 3197 / 354

Going ahead to step 6:
The number 354 fits into 3197 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 1229.0
Subtracting 3186 from 3197 leaves us with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 354

Moving on to step 7:
354 goes into 119 0 times with a remainder of 119.
Use 0 as the next digit of our solution. 
Result so far: 12290.0
If we take 0 away from 119, we end up with 119.
Include the next digit (3) from the dividend after 119, then repeat: 1193 / 354

Step 8:
354 goes into 1193 3 times with a remainder of 131.
Record the quotient 3 as the next digit in the result. 
Result so far: 122903.0
Subtract 1062 from 1193 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Moving on to step 9:
1310 divided by 354 is 3 with a remainder of 248.
Use 3 as the next digit of our solution. 
Result so far: 122903.3
Subtracting 1062 from 1310 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 10:
354 can be fit into 2480 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 122903.37
The remainder is 2 after subtracting 2478 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
354 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 122903.37
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 12:
The number 354 fits into 200 0 times, leaving a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 122903.37
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 122903.37 with a remainder of 0.002.
