311603 divided by 73 
The aim is to understand the frequency of 73 in 311603.

Advancing to step 1:
The number 73 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 73

Going ahead to step 2:
73 goes into 31 0 times with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 73

Let's proceed to step 3:
73 goes into 311 4 times with a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 292 from 311, we get 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 73

Advancing to step 4:
196 divided by 73 is 2 with a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtracting 146 from 196 leaves us with 50.
Grab the next digit (0) from the dividend, add it to 50, then carry on: 500 / 73

On to step 5:
The number 73 fits into 500 6 times, leaving a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 426.0
If we take 438 away from 500, we end up with 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 73

On to step 6:
623 divided by 73 is 8 with a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 4268.0
The remainder is 39 after subtracting 584 from 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
The number 73 fits into 390 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 4268.5
Deduct 365 from 390 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
73 goes into 250 3 times with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 4268.53
Deduct 219 from 250 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
When dividing 310 by 73, we get 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 4268.534
The remainder is 18 after subtracting 292 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
When dividing 180 by 73, we get 2 with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 4268.5342
Deduct 146 from 180 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
73 goes into 340 4 times with a remainder of 48.
The next digit of our result is 4. 
Result so far: 4268.53424
The remainder is 48 after subtracting 292 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
73 goes into 480 6 times with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 4268.534246
If we take 438 away from 480, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 13:
73 goes into 420 5 times with a remainder of 55.
The next digit of our result is 5. 
Result so far: 4268.5342465
Deduct 365 from 420 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 14:
73 can be fit into 550 7 times, resulting in a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 4268.53424657
If we subtract 511 from 550, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 4268.53424657, with a leftover of 3.9e-08.
