We're dividing 52454830 by 689 
The aim is to understand the frequency of 689 in 52454830.

On to step 1:
5 divided by 689 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 689

On to step 2:
52 divided by 689 is 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Include the next digit (4) from the dividend after 52, then repeat: 524 / 689

Moving on to step 3:
When dividing 524 by 689, we get 0 with a remainder of 524.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 524 leaves us with 524.
Include the next digit (5) from the dividend after 524, then repeat: 5245 / 689

Going ahead to step 4:
When dividing 5245 by 689, we get 7 with a remainder of 422.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 4823 from 5245, we get 422.
Take the next digit (4) from the dividend and append it to 422, then repeat: 4224 / 689

Advancing to step 5:
689 goes into 4224 6 times with a remainder of 90.
Write down 6 as next digit of the result. 
Result so far: 76.0
The remainder is 90 after subtracting 4134 from 4224.
Take the next digit (8) from the dividend and append it to 90, then repeat: 908 / 689

Going ahead to step 6:
908 divided by 689 is 1 with a remainder of 219.
Put 1 as the next digit of the answer. 
Result so far: 761.0
If we take 689 away from 908, we end up with 219.
Include the next digit (3) from the dividend after 219, then repeat: 2193 / 689

Advancing to step 7:
689 goes into 2193 3 times with a remainder of 126.
Use 3 as the next digit of our solution. 
Result so far: 7613.0
Subtract 2067 from 2193 to get 126.
Bring next digit (0) of the dividend behind the 126 and repeat the process: 1260 / 689

Let's proceed to step 8:
The number 689 fits into 1260 1 times, leaving a remainder of 571.
The next digit of our result is 1. 
Result so far: 76131.0
Subtract 689 from 1260 to get 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Let's proceed to step 9:
If we divide 5710 by 689, we get 8 and a remainder of 198.
Use 8 as the next digit of our solution. 
Result so far: 76131.8
Subtract 5512 from 5710 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 10:
The number 689 fits into 1980 2 times, leaving a remainder of 602.
Record the quotient 2 as the next digit in the result. 
Result so far: 76131.82
If we subtract 1378 from 1980, we get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Moving on to step 11:
If we divide 6020 by 689, we get 8 and a remainder of 508.
Record the quotient 8 as the next digit in the result. 
Result so far: 76131.828
Subtract 5512 from 6020 to get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Let's proceed to step 12:
689 goes into 5080 7 times with a remainder of 257.
The next digit of our result is 7. 
Result so far: 76131.8287
The remainder is 257 after subtracting 4823 from 5080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Advancing to step 13:
689 can be fit into 2570 3 times, resulting in a remainder of 503.
The number 3 becomes the next digit in our result. 
Result so far: 76131.82873
Subtract 2067 from 2570 to get 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Advancing to step 14:
689 goes into 5030 7 times with a remainder of 207.
Put 7 as the next digit of the answer. 
Result so far: 76131.828737
If we take 4823 away from 5030, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Going ahead to step 15:
2070 divided by 689 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 76131.8287373
If we take 2067 away from 2070, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 16:
If we divide 30 by 689, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 76131.8287373
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 76131.8287373, with a leftover of 3e-08.
