We look at the division of 373003 by 628 
The aim is to understand the frequency of 628 in 373003.

On to step 1:
When dividing 3 by 628, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 628

Going ahead to step 2:
When dividing 37 by 628, we get 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 628

Moving on to step 3:
If we divide 373 by 628, we get 0 and a remainder of 373.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 373 after subtracting 0 from 373.
Append the next digit (0) from the dividend to 373 and continue with: 3730 / 628

Let's proceed to step 4:
628 goes into 3730 5 times with a remainder of 590.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 590 after subtracting 3140 from 3730.
Take the next digit (0) from the dividend and append it to 590, then repeat: 5900 / 628

Step 5:
The number 628 fits into 5900 9 times, leaving a remainder of 248.
The next digit of our result is 9. 
Result so far: 59.0
Subtract 5652 from 5900 to get 248.
Fetch the next digit (3) from the dividend, attach it to 248 and continue: 2483 / 628

Moving on to step 6:
The number 628 fits into 2483 3 times, leaving a remainder of 599.
Put 3 as the next digit of the answer. 
Result so far: 593.0
If we take 1884 away from 2483, we end up with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Let's proceed to step 7:
If we divide 5990 by 628, we get 9 and a remainder of 338.
The number 9 becomes the next digit in our result. 
Result so far: 593.9
Subtract 5652 from 5990 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Step 8:
The number 628 fits into 3380 5 times, leaving a remainder of 240.
The next digit of our result is 5. 
Result so far: 593.95
If we subtract 3140 from 3380, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 9:
The number 628 fits into 2400 3 times, leaving a remainder of 516.
Record the quotient 3 as the next digit in the result. 
Result so far: 593.953
Subtract 1884 from 2400 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Moving on to step 10:
The number 628 fits into 5160 8 times, leaving a remainder of 136.
Use 8 as the next digit of our solution. 
Result so far: 593.9538
The remainder is 136 after subtracting 5024 from 5160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 11:
The number 628 fits into 1360 2 times, leaving a remainder of 104.
Record the quotient 2 as the next digit in the result. 
Result so far: 593.95382
If we subtract 1256 from 1360, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 12:
If we divide 1040 by 628, we get 1 and a remainder of 412.
The next digit of our result is 1. 
Result so far: 593.953821
Subtract 628 from 1040 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 13:
The number 628 fits into 4120 6 times, leaving a remainder of 352.
The number 6 becomes the next digit in our result. 
Result so far: 593.9538216
Subtracting 3768 from 4120 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 14:
628 goes into 3520 5 times with a remainder of 380.
Record the quotient 5 as the next digit in the result. 
Result so far: 593.95382165
Deduct 3140 from 3520 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final result is 593.95382165 with a remainder of 3.8e-07.
