53265909 ÷ 907 
The aim is to understand the frequency of 907 in 53265909.

Going ahead to step 1:
If we divide 5 by 907, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 907

Step 2:
The number 907 fits into 53 0 times, leaving a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Grab the next digit (2) from the dividend, add it to 53, then carry on: 532 / 907

Going ahead to step 3:
The number 907 fits into 532 0 times, leaving a remainder of 532.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 532 after subtracting 0 from 532.
Include the next digit (6) from the dividend after 532, then repeat: 5326 / 907

Going ahead to step 4:
907 can be fit into 5326 5 times, resulting in a remainder of 791.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 791 after subtracting 4535 from 5326.
Bring next digit (5) of the dividend behind the 791 and repeat the process: 7915 / 907

Let's proceed to step 5:
When dividing 7915 by 907, we get 8 with a remainder of 659.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Deduct 7256 from 7915 and we're left with 659.
Include the next digit (9) from the dividend after 659, then repeat: 6599 / 907

On to step 6:
907 goes into 6599 7 times with a remainder of 250.
Put 7 as the next digit of the answer. 
Result so far: 587.0
If we take 6349 away from 6599, we end up with 250.
Fetch the next digit (0) from the dividend, attach it to 250 and continue: 2500 / 907

Advancing to step 7:
When dividing 2500 by 907, we get 2 with a remainder of 686.
Record the quotient 2 as the next digit in the result. 
Result so far: 5872.0
If we take 1814 away from 2500, we end up with 686.
Include the next digit (9) from the dividend after 686, then repeat: 6869 / 907

Step 8:
If we divide 6869 by 907, we get 7 and a remainder of 520.
Record the quotient 7 as the next digit in the result. 
Result so far: 58727.0
If we take 6349 away from 6869, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 9:
5200 divided by 907 is 5 with a remainder of 665.
Record the quotient 5 as the next digit in the result. 
Result so far: 58727.5
Deduct 4535 from 5200 and we're left with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Going ahead to step 10:
907 goes into 6650 7 times with a remainder of 301.
The number 7 becomes the next digit in our result. 
Result so far: 58727.57
If we subtract 6349 from 6650, we get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 11:
The number 907 fits into 3010 3 times, leaving a remainder of 289.
Write down 3 as next digit of the result. 
Result so far: 58727.573
Subtract 2721 from 3010 to get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Moving on to step 12:
2890 divided by 907 is 3 with a remainder of 169.
Record the quotient 3 as the next digit in the result. 
Result so far: 58727.5733
Subtract 2721 from 2890 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

The final outcome is 58727.5733, with a leftover of 0.00169.
