We look at the division of 18789373 by 763 
The aim is to understand the frequency of 763 in 18789373.

Advancing to step 1:
When dividing 1 by 763, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 763

Step 2:
18 divided by 763 is 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 763

Step 3:
If we divide 187 by 763, we get 0 and a remainder of 187.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 187 after subtracting 0 from 187.
Bring next digit (8) of the dividend behind the 187 and repeat the process: 1878 / 763

Step 4:
1878 divided by 763 is 2 with a remainder of 352.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1526 from 1878 and we're left with 352.
Fetch the next digit (9) from the dividend, attach it to 352 and continue: 3529 / 763

Step 5:
The number 763 fits into 3529 4 times, leaving a remainder of 477.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 3052 from 3529, we get 477.
Include the next digit (3) from the dividend after 477, then repeat: 4773 / 763

Going ahead to step 6:
763 goes into 4773 6 times with a remainder of 195.
The next digit of our result is 6. 
Result so far: 246.0
Deduct 4578 from 4773 and we're left with 195.
Append the next digit (7) from the dividend to 195 and continue with: 1957 / 763

On to step 7:
If we divide 1957 by 763, we get 2 and a remainder of 431.
The number 2 becomes the next digit in our result. 
Result so far: 2462.0
If we subtract 1526 from 1957, we get 431.
Include the next digit (3) from the dividend after 431, then repeat: 4313 / 763

Going ahead to step 8:
If we divide 4313 by 763, we get 5 and a remainder of 498.
Put 5 as the next digit of the answer. 
Result so far: 24625.0
Subtracting 3815 from 4313 leaves us with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Advancing to step 9:
763 can be fit into 4980 6 times, resulting in a remainder of 402.
Use 6 as the next digit of our solution. 
Result so far: 24625.6
The remainder is 402 after subtracting 4578 from 4980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Moving on to step 10:
4020 divided by 763 is 5 with a remainder of 205.
The next digit of our result is 5. 
Result so far: 24625.65
If we subtract 3815 from 4020, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 11:
When dividing 2050 by 763, we get 2 with a remainder of 524.
Write down 2 as next digit of the result. 
Result so far: 24625.652
Subtracting 1526 from 2050 leaves us with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Let's proceed to step 12:
When dividing 5240 by 763, we get 6 with a remainder of 662.
Write down 6 as next digit of the result. 
Result so far: 24625.6526
Subtracting 4578 from 5240 leaves us with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Let's proceed to step 13:
If we divide 6620 by 763, we get 8 and a remainder of 516.
The number 8 becomes the next digit in our result. 
Result so far: 24625.65268
If we subtract 6104 from 6620, we 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.

Step 14:
If we divide 5160 by 763, we get 6 and a remainder of 582.
Record the quotient 6 as the next digit in the result. 
Result so far: 24625.652686
Deduct 4578 from 5160 and we're left with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

On to step 15:
763 can be fit into 5820 7 times, resulting in a remainder of 479.
The next digit of our result is 7. 
Result so far: 24625.6526867
Deduct 5341 from 5820 and we're left with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Let's proceed to step 16:
763 goes into 4790 6 times with a remainder of 212.
Record the quotient 6 as the next digit in the result. 
Result so far: 24625.65268676
Subtract 4578 from 4790 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The final result is 24625.65268676 with a remainder of 2.12e-07.
