8432894 ÷ 907 
The aim is to understand the frequency of 907 in 8432894.

Moving on to step 1:
907 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 907

On to step 2:
If we divide 84 by 907, we get 0 and a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Bring next digit (3) of the dividend behind the 84 and repeat the process: 843 / 907

Going ahead to step 3:
When dividing 843 by 907, we get 0 with a remainder of 843.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 843, we get 843.
Grab the next digit (2) from the dividend, add it to 843, then carry on: 8432 / 907

Advancing to step 4:
If we divide 8432 by 907, we get 9 and a remainder of 269.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 8163 from 8432, we get 269.
Grab the next digit (8) from the dividend, add it to 269, then carry on: 2698 / 907

On to step 5:
The number 907 fits into 2698 2 times, leaving a remainder of 884.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
The remainder is 884 after subtracting 1814 from 2698.
Fetch the next digit (9) from the dividend, attach it to 884 and continue: 8849 / 907

Moving on to step 6:
907 goes into 8849 9 times with a remainder of 686.
Record the quotient 9 as the next digit in the result. 
Result so far: 929.0
If we subtract 8163 from 8849, we get 686.
Append the next digit (4) from the dividend to 686 and continue with: 6864 / 907

Going ahead to step 7:
907 can be fit into 6864 7 times, resulting in a remainder of 515.
Write down 7 as next digit of the result. 
Result so far: 9297.0
The remainder is 515 after subtracting 6349 from 6864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Moving on to step 8:
The number 907 fits into 5150 5 times, leaving a remainder of 615.
The next digit of our result is 5. 
Result so far: 9297.5
If we take 4535 away from 5150, we end up with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

On to step 9:
When dividing 6150 by 907, we get 6 with a remainder of 708.
The number 6 becomes the next digit in our result. 
Result so far: 9297.56
If we take 5442 away from 6150, we end up with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

On to step 10:
If we divide 7080 by 907, we get 7 and a remainder of 731.
Write down 7 as next digit of the result. 
Result so far: 9297.567
Deduct 6349 from 7080 and we're left with 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Advancing to step 11:
907 goes into 7310 8 times with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 9297.5678
Subtracting 7256 from 7310 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
540 divided by 907 is 0 with a remainder of 540.
Record the quotient 0 as the next digit in the result. 
Result so far: 9297.5678
Deduct 0 from 540 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 13:
If we divide 5400 by 907, we get 5 and a remainder of 865.
Write down 5 as next digit of the result. 
Result so far: 9297.567805
If we take 4535 away from 5400, we end up with 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

On to step 14:
When dividing 8650 by 907, we get 9 with a remainder of 487.
Record the quotient 9 as the next digit in the result. 
Result so far: 9297.5678059
The remainder is 487 after subtracting 8163 from 8650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Moving on to step 15:
907 can be fit into 4870 5 times, resulting in a remainder of 335.
The number 5 becomes the next digit in our result. 
Result so far: 9297.56780595
The remainder is 335 after subtracting 4535 from 4870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

The final result is 9297.56780595 with a remainder of 3.35e-07.
