We divide 13487680 by 907
The aim is to understand the frequency of 907 in 13487680.

Moving on to step 1:
If we divide 1 by 907, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 907

Moving on to step 2:
907 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 907

Going ahead to step 3:
If we divide 134 by 907, we get 0 and a remainder of 134.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 134 and we're left with 134.
Bring next digit (8) of the dividend behind the 134 and repeat the process: 1348 / 907

Advancing to step 4:
907 goes into 1348 1 times with a remainder of 441.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 907 from 1348 and we're left with 441.
Append the next digit (7) from the dividend to 441 and continue with: 4417 / 907

On to step 5:
4417 divided by 907 is 4 with a remainder of 789.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 3628 from 4417 and we're left with 789.
Take the next digit (6) from the dividend and append it to 789, then repeat: 7896 / 907

Let's proceed to step 6:
907 goes into 7896 8 times with a remainder of 640.
Write down 8 as next digit of the result. 
Result so far: 148.0
Deduct 7256 from 7896 and we're left with 640.
Grab the next digit (8) from the dividend, add it to 640, then carry on: 6408 / 907

On to step 7:
907 can be fit into 6408 7 times, resulting in a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 1487.0
Subtract 6349 from 6408 to get 59.
Append the next digit (0) from the dividend to 59 and continue with: 590 / 907

On to step 8:
If we divide 590 by 907, we get 0 and a remainder of 590.
Put 0 as the next digit of the answer. 
Result so far: 14870.0
If we subtract 0 from 590, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 9:
907 goes into 5900 6 times with a remainder of 458.
Write down 6 as next digit of the result. 
Result so far: 14870.6
Deduct 5442 from 5900 and we're left with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Going ahead to step 10:
4580 divided by 907 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 14870.65
If we take 4535 away from 4580, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 11:
The number 907 fits into 450 0 times, leaving a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 14870.65
If we take 0 away from 450, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 12:
The number 907 fits into 4500 4 times, leaving a remainder of 872.
Put 4 as the next digit of the answer. 
Result so far: 14870.6504
Subtracting 3628 from 4500 leaves us with 872.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8720, and continue the process.

Advancing to step 13:
The number 907 fits into 8720 9 times, leaving a remainder of 557.
The number 9 becomes the next digit in our result. 
Result so far: 14870.65049
Subtract 8163 from 8720 to get 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Let's proceed to step 14:
907 can be fit into 5570 6 times, resulting in a remainder of 128.
Record the quotient 6 as the next digit in the result. 
Result so far: 14870.650496
The remainder is 128 after subtracting 5442 from 5570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 15:
If we divide 1280 by 907, we get 1 and a remainder of 373.
Record the quotient 1 as the next digit in the result. 
Result so far: 14870.6504961
If we take 907 away from 1280, we end up with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Advancing to step 16:
When dividing 3730 by 907, we get 4 with a remainder of 102.
Record the quotient 4 as the next digit in the result. 
Result so far: 14870.65049614
Subtracting 3628 from 3730 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final outcome is 14870.65049614, with a leftover of 1.02e-07.
