We divide 308109 by 73
The aim is to understand the frequency of 73 in 308109.

Advancing to step 1:
73 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 73

On to step 2:
If we divide 30 by 73, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 73

Let's proceed to step 3:
73 can be fit into 308 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 292 away from 308, we end up with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 73

Let's proceed to step 4:
The number 73 fits into 161 2 times, leaving a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtracting 146 from 161 leaves us with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 73

Advancing to step 5:
150 divided by 73 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 422.0
If we subtract 146 from 150, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 73

Advancing to step 6:
The number 73 fits into 49 0 times, leaving a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 4220.0
Subtracting 0 from 49 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
73 can be fit into 490 6 times, resulting in a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 4220.6
The remainder is 52 after subtracting 438 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 8:
73 can be fit into 520 7 times, resulting in a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 4220.67
If we subtract 511 from 520, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
73 goes into 90 1 times with a remainder of 17.
The next digit of our result is 1. 
Result so far: 4220.671
Subtract 73 from 90 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
170 divided by 73 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 4220.6712
Deduct 146 from 170 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.

Let's proceed to step 11:
73 can be fit into 240 3 times, resulting in a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 4220.67123
If we subtract 219 from 240, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 12:
The number 73 fits into 210 2 times, leaving a remainder of 64.
The next digit of our result is 2. 
Result so far: 4220.671232
The remainder is 64 after subtracting 146 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 13:
When dividing 640 by 73, we get 8 with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 4220.6712328
If we take 584 away from 640, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
If we divide 560 by 73, we get 7 and a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 4220.67123287
Deduct 511 from 560 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final outcome is 4220.67123287, with a leftover of 4.9e-08.
