We divide 43479766 by 909
The aim is to understand the frequency of 909 in 43479766.

Advancing to step 1:
When dividing 4 by 909, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 909

Moving on to step 2:
909 can be fit into 43 0 times, resulting in a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 909

Going ahead to step 3:
When dividing 434 by 909, we get 0 with a remainder of 434.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 434 after subtracting 0 from 434.
Fetch the next digit (7) from the dividend, attach it to 434 and continue: 4347 / 909

On to step 4:
When dividing 4347 by 909, we get 4 with a remainder of 711.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 711 after subtracting 3636 from 4347.
Take the next digit (9) from the dividend and append it to 711, then repeat: 7119 / 909

Advancing to step 5:
909 can be fit into 7119 7 times, resulting in a remainder of 756.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we take 6363 away from 7119, we end up with 756.
Grab the next digit (7) from the dividend, add it to 756, then carry on: 7567 / 909

Step 6:
909 goes into 7567 8 times with a remainder of 295.
Put 8 as the next digit of the answer. 
Result so far: 478.0
If we take 7272 away from 7567, we end up with 295.
Bring next digit (6) of the dividend behind the 295 and repeat the process: 2956 / 909

Moving on to step 7:
The number 909 fits into 2956 3 times, leaving a remainder of 229.
The number 3 becomes the next digit in our result. 
Result so far: 4783.0
Deduct 2727 from 2956 and we're left with 229.
Take the next digit (6) from the dividend and append it to 229, then repeat: 2296 / 909

Going ahead to step 8:
The number 909 fits into 2296 2 times, leaving a remainder of 478.
The next digit of our result is 2. 
Result so far: 47832.0
Subtract 1818 from 2296 to get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Let's proceed to step 9:
909 goes into 4780 5 times with a remainder of 235.
Write down 5 as next digit of the result. 
Result so far: 47832.5
Subtract 4545 from 4780 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 10:
909 goes into 2350 2 times with a remainder of 532.
Use 2 as the next digit of our solution. 
Result so far: 47832.52
If we take 1818 away from 2350, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Moving on to step 11:
909 can be fit into 5320 5 times, resulting in a remainder of 775.
Record the quotient 5 as the next digit in the result. 
Result so far: 47832.525
If we subtract 4545 from 5320, we get 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

On to step 12:
When dividing 7750 by 909, we get 8 with a remainder of 478.
The next digit of our result is 8. 
Result so far: 47832.5258
If we subtract 7272 from 7750, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Moving on to step 13:
909 goes into 4780 5 times with a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 47832.52585
Deduct 4545 from 4780 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 14:
When dividing 2350 by 909, we get 2 with a remainder of 532.
Put 2 as the next digit of the answer. 
Result so far: 47832.525852
If we subtract 1818 from 2350, we get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Step 15:
909 can be fit into 5320 5 times, resulting in a remainder of 775.
Record the quotient 5 as the next digit in the result. 
Result so far: 47832.5258525
Subtract 4545 from 5320 to get 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Moving on to step 16:
The number 909 fits into 7750 8 times, leaving a remainder of 478.
Use 8 as the next digit of our solution. 
Result so far: 47832.52585258
If we subtract 7272 from 7750, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

In conclusion, the division gives 47832.52585258 with a balance of 4.78e-07.
