We divide 8158439 by 907
The aim is to understand the frequency of 907 in 8158439.

Going ahead to step 1:
907 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 907

Let's proceed to step 2:
907 goes into 81 0 times with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Include the next digit (5) from the dividend after 81, then repeat: 815 / 907

Going ahead to step 3:
907 can be fit into 815 0 times, resulting in a remainder of 815.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 815, we end up with 815.
Grab the next digit (8) from the dividend, add it to 815, then carry on: 8158 / 907

Moving on to step 4:
907 can be fit into 8158 8 times, resulting in a remainder of 902.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 7256 away from 8158, we end up with 902.
Fetch the next digit (4) from the dividend, attach it to 902 and continue: 9024 / 907

On to step 5:
When dividing 9024 by 907, we get 9 with a remainder of 861.
Put 9 as the next digit of the answer. 
Result so far: 89.0
The remainder is 861 after subtracting 8163 from 9024.
Append the next digit (3) from the dividend to 861 and continue with: 8613 / 907

Let's proceed to step 6:
When dividing 8613 by 907, we get 9 with a remainder of 450.
Put 9 as the next digit of the answer. 
Result so far: 899.0
Subtracting 8163 from 8613 leaves us with 450.
Grab the next digit (9) from the dividend, add it to 450, then carry on: 4509 / 907

Advancing to step 7:
If we divide 4509 by 907, we get 4 and a remainder of 881.
The next digit of our result is 4. 
Result so far: 8994.0
Subtract 3628 from 4509 to get 881.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8810, and continue the process.

Advancing to step 8:
When dividing 8810 by 907, we get 9 with a remainder of 647.
The number 9 becomes the next digit in our result. 
Result so far: 8994.9
The remainder is 647 after subtracting 8163 from 8810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Advancing to step 9:
The number 907 fits into 6470 7 times, leaving a remainder of 121.
Record the quotient 7 as the next digit in the result. 
Result so far: 8994.97
Subtract 6349 from 6470 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 10:
1210 divided by 907 is 1 with a remainder of 303.
The next digit of our result is 1. 
Result so far: 8994.971
If we take 907 away from 1210, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Moving on to step 11:
907 can be fit into 3030 3 times, resulting in a remainder of 309.
Put 3 as the next digit of the answer. 
Result so far: 8994.9713
Deduct 2721 from 3030 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Step 12:
907 goes into 3090 3 times with a remainder of 369.
Record the quotient 3 as the next digit in the result. 
Result so far: 8994.97133
Subtract 2721 from 3090 to get 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

The quotient of the division is 8994.97133, and the remainder is 0.000369.
