We look at the division of 17602102 by 763 
The aim is to understand the frequency of 763 in 17602102.

Moving on to step 1:
The number 763 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 763

On to step 2:
The number 763 fits into 17 0 times, leaving a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 763

Moving on to step 3:
When dividing 176 by 763, we get 0 with a remainder of 176.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 176, we get 176.
Fetch the next digit (0) from the dividend, attach it to 176 and continue: 1760 / 763

On to step 4:
If we divide 1760 by 763, we get 2 and a remainder of 234.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1526 from 1760 and we're left with 234.
Fetch the next digit (2) from the dividend, attach it to 234 and continue: 2342 / 763

On to step 5:
The number 763 fits into 2342 3 times, leaving a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 2289 from 2342 and we're left with 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 763

Moving on to step 6:
When dividing 531 by 763, we get 0 with a remainder of 531.
The number 0 becomes the next digit in our result. 
Result so far: 230.0
The remainder is 531 after subtracting 0 from 531.
Fetch the next digit (0) from the dividend, attach it to 531 and continue: 5310 / 763

Step 7:
When dividing 5310 by 763, we get 6 with a remainder of 732.
Put 6 as the next digit of the answer. 
Result so far: 2306.0
Subtract 4578 from 5310 to get 732.
Grab the next digit (2) from the dividend, add it to 732, then carry on: 7322 / 763

On to step 8:
The number 763 fits into 7322 9 times, leaving a remainder of 455.
Record the quotient 9 as the next digit in the result. 
Result so far: 23069.0
The remainder is 455 after subtracting 6867 from 7322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

On to step 9:
763 goes into 4550 5 times with a remainder of 735.
Use 5 as the next digit of our solution. 
Result so far: 23069.5
If we take 3815 away from 4550, we end up with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Moving on to step 10:
The number 763 fits into 7350 9 times, leaving a remainder of 483.
The next digit of our result is 9. 
Result so far: 23069.59
If we take 6867 away from 7350, we end up with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Advancing to step 11:
763 goes into 4830 6 times with a remainder of 252.
Put 6 as the next digit of the answer. 
Result so far: 23069.596
The remainder is 252 after subtracting 4578 from 4830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 12:
763 can be fit into 2520 3 times, resulting in a remainder of 231.
Record the quotient 3 as the next digit in the result. 
Result so far: 23069.5963
Deduct 2289 from 2520 and we're left with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 13:
When dividing 2310 by 763, we get 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 23069.59633
If we take 2289 away from 2310, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 23069.59633, with a leftover of 2.1e-05.
