We're dividing 52986876 by 689 
The aim is to understand the frequency of 689 in 52986876.

Going ahead to step 1:
The number 689 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 689

Advancing to step 2:
The number 689 fits into 52 0 times, leaving a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Append the next digit (9) from the dividend to 52 and continue with: 529 / 689

Let's proceed to step 3:
689 goes into 529 0 times with a remainder of 529.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 529, we end up with 529.
Grab the next digit (8) from the dividend, add it to 529, then carry on: 5298 / 689

On to step 4:
If we divide 5298 by 689, we get 7 and a remainder of 475.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 475 after subtracting 4823 from 5298.
Grab the next digit (6) from the dividend, add it to 475, then carry on: 4756 / 689

Advancing to step 5:
689 goes into 4756 6 times with a remainder of 622.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
Deduct 4134 from 4756 and we're left with 622.
Bring next digit (8) of the dividend behind the 622 and repeat the process: 6228 / 689

Let's proceed to step 6:
When dividing 6228 by 689, we get 9 with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 769.0
Deduct 6201 from 6228 and we're left with 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 689

Advancing to step 7:
689 can be fit into 277 0 times, resulting in a remainder of 277.
Record the quotient 0 as the next digit in the result. 
Result so far: 7690.0
The remainder is 277 after subtracting 0 from 277.
Fetch the next digit (6) from the dividend, attach it to 277 and continue: 2776 / 689

Going ahead to step 8:
689 goes into 2776 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 76904.0
If we subtract 2756 from 2776, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
The number 689 fits into 200 0 times, leaving a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 76904.0
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 10:
If we divide 2000 by 689, we get 2 and a remainder of 622.
Put 2 as the next digit of the answer. 
Result so far: 76904.02
If we subtract 1378 from 2000, we get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Going ahead to step 11:
If we divide 6220 by 689, we get 9 and a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 76904.029
Deduct 6201 from 6220 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
689 goes into 190 0 times with a remainder of 190.
Write down 0 as next digit of the result. 
Result so far: 76904.029
If we take 0 away from 190, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 13:
1900 divided by 689 is 2 with a remainder of 522.
Record the quotient 2 as the next digit in the result. 
Result so far: 76904.02902
Deduct 1378 from 1900 and we're left with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Step 14:
689 goes into 5220 7 times with a remainder of 397.
Put 7 as the next digit of the answer. 
Result so far: 76904.029027
The remainder is 397 after subtracting 4823 from 5220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Going ahead to step 15:
When dividing 3970 by 689, we get 5 with a remainder of 525.
The next digit of our result is 5. 
Result so far: 76904.0290275
Deduct 3445 from 3970 and we're left with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Advancing to step 16:
689 can be fit into 5250 7 times, resulting in a remainder of 427.
The next digit of our result is 7. 
Result so far: 76904.02902757
Deduct 4823 from 5250 and we're left with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

The final outcome is 76904.02902757, with a leftover of 4.27e-07.
