Let's divide 43988618 by 907
The aim is to understand the frequency of 907 in 43988618.

Step 1:
If we divide 4 by 907, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 907

Going ahead to step 2:
When dividing 43 by 907, we get 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 907

Step 3:
907 can be fit into 439 0 times, resulting in a remainder of 439.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 439 and we're left with 439.
Grab the next digit (8) from the dividend, add it to 439, then carry on: 4398 / 907

Let's proceed to step 4:
907 goes into 4398 4 times with a remainder of 770.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 3628 from 4398 and we're left with 770.
Include the next digit (8) from the dividend after 770, then repeat: 7708 / 907

Advancing to step 5:
7708 divided by 907 is 8 with a remainder of 452.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
The remainder is 452 after subtracting 7256 from 7708.
Grab the next digit (6) from the dividend, add it to 452, then carry on: 4526 / 907

Moving on to step 6:
When dividing 4526 by 907, we get 4 with a remainder of 898.
Use 4 as the next digit of our solution. 
Result so far: 484.0
Deduct 3628 from 4526 and we're left with 898.
Include the next digit (1) from the dividend after 898, then repeat: 8981 / 907

Let's proceed to step 7:
907 goes into 8981 9 times with a remainder of 818.
Write down 9 as next digit of the result. 
Result so far: 4849.0
Subtract 8163 from 8981 to get 818.
Take the next digit (8) from the dividend and append it to 818, then repeat: 8188 / 907

Advancing to step 8:
When dividing 8188 by 907, we get 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 48499.0
Subtract 8163 from 8188 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
907 can be fit into 250 0 times, resulting in a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 48499.0
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 10:
When dividing 2500 by 907, we get 2 with a remainder of 686.
The next digit of our result is 2. 
Result so far: 48499.02
Subtract 1814 from 2500 to get 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Advancing to step 11:
If we divide 6860 by 907, we get 7 and a remainder of 511.
Write down 7 as next digit of the result. 
Result so far: 48499.027
Subtract 6349 from 6860 to get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Step 12:
5110 divided by 907 is 5 with a remainder of 575.
Use 5 as the next digit of our solution. 
Result so far: 48499.0275
If we subtract 4535 from 5110, we get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

On to step 13:
5750 divided by 907 is 6 with a remainder of 308.
Use 6 as the next digit of our solution. 
Result so far: 48499.02756
Deduct 5442 from 5750 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 14:
If we divide 3080 by 907, we get 3 and a remainder of 359.
Record the quotient 3 as the next digit in the result. 
Result so far: 48499.027563
Subtract 2721 from 3080 to get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Going ahead to step 15:
907 can be fit into 3590 3 times, resulting in a remainder of 869.
Record the quotient 3 as the next digit in the result. 
Result so far: 48499.0275633
Subtract 2721 from 3590 to get 869.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8690, and continue the process.

The final outcome is 48499.0275633, with a leftover of 8.69e-06.
