We're dividing 51492663 by 907 
The aim is to understand the frequency of 907 in 51492663.

Advancing to step 1:
If we divide 5 by 907, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 907

Let's proceed to step 2:
When dividing 51 by 907, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 907

Advancing to step 3:
If we divide 514 by 907, we get 0 and a remainder of 514.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 514, we end up with 514.
Fetch the next digit (9) from the dividend, attach it to 514 and continue: 5149 / 907

Let's proceed to step 4:
907 can be fit into 5149 5 times, resulting in a remainder of 614.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 4535 from 5149 to get 614.
Grab the next digit (2) from the dividend, add it to 614, then carry on: 6142 / 907

On to step 5:
If we divide 6142 by 907, we get 6 and a remainder of 700.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Subtract 5442 from 6142 to get 700.
Bring next digit (6) of the dividend behind the 700 and repeat the process: 7006 / 907

On to step 6:
If we divide 7006 by 907, we get 7 and a remainder of 657.
Put 7 as the next digit of the answer. 
Result so far: 567.0
If we subtract 6349 from 7006, we get 657.
Append the next digit (6) from the dividend to 657 and continue with: 6576 / 907

Moving on to step 7:
When dividing 6576 by 907, we get 7 with a remainder of 227.
Write down 7 as next digit of the result. 
Result so far: 5677.0
Subtracting 6349 from 6576 leaves us with 227.
Bring next digit (3) of the dividend behind the 227 and repeat the process: 2273 / 907

Going ahead to step 8:
907 can be fit into 2273 2 times, resulting in a remainder of 459.
The number 2 becomes the next digit in our result. 
Result so far: 56772.0
Deduct 1814 from 2273 and we're left with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Step 9:
When dividing 4590 by 907, we get 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 56772.5
The remainder is 55 after subtracting 4535 from 4590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
907 goes into 550 0 times with a remainder of 550.
Put 0 as the next digit of the answer. 
Result so far: 56772.5
Deduct 0 from 550 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 11:
5500 divided by 907 is 6 with a remainder of 58.
The number 6 becomes the next digit in our result. 
Result so far: 56772.506
Deduct 5442 from 5500 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
The number 907 fits into 580 0 times, leaving a remainder of 580.
Use 0 as the next digit of our solution. 
Result so far: 56772.506
Deduct 0 from 580 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 13:
The number 907 fits into 5800 6 times, leaving a remainder of 358.
Write down 6 as next digit of the result. 
Result so far: 56772.50606
If we subtract 5442 from 5800, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Moving on to step 14:
907 goes into 3580 3 times with a remainder of 859.
The next digit of our result is 3. 
Result so far: 56772.506063
If we take 2721 away from 3580, we end up with 859.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8590, and continue the process.

Moving on to step 15:
907 goes into 8590 9 times with a remainder of 427.
Write down 9 as next digit of the result. 
Result so far: 56772.5060639
Subtracting 8163 from 8590 leaves us 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.

Moving on to step 16:
If we divide 4270 by 907, we get 4 and a remainder of 642.
The number 4 becomes the next digit in our result. 
Result so far: 56772.50606394
If we take 3628 away from 4270, we end up with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

After the division, we end up with 56772.50606394 and a remainder of 6.42e-07.
