We're dividing 25949707 by 689 
The aim is to understand the frequency of 689 in 25949707.

On to step 1:
689 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 689

On to step 2:
689 goes into 25 0 times with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 689

Advancing to step 3:
689 goes into 259 0 times with a remainder of 259.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 259 leaves us with 259.
Bring next digit (4) of the dividend behind the 259 and repeat the process: 2594 / 689

Advancing to step 4:
2594 divided by 689 is 3 with a remainder of 527.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 527 after subtracting 2067 from 2594.
Append the next digit (9) from the dividend to 527 and continue with: 5279 / 689

On to step 5:
The number 689 fits into 5279 7 times, leaving a remainder of 456.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
The remainder is 456 after subtracting 4823 from 5279.
Bring next digit (7) of the dividend behind the 456 and repeat the process: 4567 / 689

On to step 6:
The number 689 fits into 4567 6 times, leaving a remainder of 433.
Write down 6 as next digit of the result. 
Result so far: 376.0
The remainder is 433 after subtracting 4134 from 4567.
Append the next digit (0) from the dividend to 433 and continue with: 4330 / 689

Moving on to step 7:
689 goes into 4330 6 times with a remainder of 196.
Use 6 as the next digit of our solution. 
Result so far: 3766.0
The remainder is 196 after subtracting 4134 from 4330.
Take the next digit (7) from the dividend and append it to 196, then repeat: 1967 / 689

On to step 8:
1967 divided by 689 is 2 with a remainder of 589.
Use 2 as the next digit of our solution. 
Result so far: 37662.0
Subtracting 1378 from 1967 leaves us with 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Advancing to step 9:
5890 divided by 689 is 8 with a remainder of 378.
Put 8 as the next digit of the answer. 
Result so far: 37662.8
Deduct 5512 from 5890 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 10:
The number 689 fits into 3780 5 times, leaving a remainder of 335.
Write down 5 as next digit of the result. 
Result so far: 37662.85
If we take 3445 away from 3780, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 11:
3350 divided by 689 is 4 with a remainder of 594.
Write down 4 as next digit of the result. 
Result so far: 37662.854
Subtracting 2756 from 3350 leaves us with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

On to step 12:
5940 divided by 689 is 8 with a remainder of 428.
Record the quotient 8 as the next digit in the result. 
Result so far: 37662.8548
If we subtract 5512 from 5940, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 13:
689 goes into 4280 6 times with a remainder of 146.
Use 6 as the next digit of our solution. 
Result so far: 37662.85486
If we take 4134 away from 4280, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 14:
689 goes into 1460 2 times with a remainder of 82.
Write down 2 as next digit of the result. 
Result so far: 37662.854862
Subtract 1378 from 1460 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 15:
689 can be fit into 820 1 times, resulting in a remainder of 131.
Write down 1 as next digit of the result. 
Result so far: 37662.8548621
Deduct 689 from 820 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Let's proceed to step 16:
689 can be fit into 1310 1 times, resulting in a remainder of 621.
Use 1 as the next digit of our solution. 
Result so far: 37662.85486211
Deduct 689 from 1310 and we're left with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

The quotient of the division is 37662.85486211, and the remainder is 6.21e-07.
