We look at the division of 437840 by 83 
The aim is to understand the frequency of 83 in 437840.

Let's proceed to step 1:
If we divide 4 by 83, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 83

Let's proceed to step 2:
The number 83 fits into 43 0 times, leaving a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 83

Step 3:
83 goes into 437 5 times with a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 415 from 437 to get 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 83

Going ahead to step 4:
228 divided by 83 is 2 with a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we subtract 166 from 228, we get 62.
Fetch the next digit (4) from the dividend, attach it to 62 and continue: 624 / 83

Advancing to step 5:
624 divided by 83 is 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 527.0
The remainder is 43 after subtracting 581 from 624.
Take the next digit (0) from the dividend and append it to 43, then repeat: 430 / 83

Let's proceed to step 6:
83 goes into 430 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 5275.0
If we take 415 away from 430, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
83 goes into 150 1 times with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 5275.1
Deduct 83 from 150 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 8:
When dividing 670 by 83, we get 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 5275.18
The remainder is 6 after subtracting 664 from 670.
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 9:
If we divide 60 by 83, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 5275.18
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
600 divided by 83 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 5275.1807
If we subtract 581 from 600, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 11:
83 can be fit into 190 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 5275.18072
Deduct 166 from 190 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
When dividing 240 by 83, we get 2 with a remainder of 74.
Record the quotient 2 as the next digit in the result. 
Result so far: 5275.180722
The remainder is 74 after subtracting 166 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final result is 5275.180722 with a remainder of 7.4e-06.
