We're dividing 43420526 by 902 
The aim is to understand the frequency of 902 in 43420526.

Step 1:
902 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 902

Let's proceed to step 2:
902 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 902

Step 3:
434 divided by 902 is 0 with a remainder of 434.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 434, we get 434.
Bring next digit (2) of the dividend behind the 434 and repeat the process: 4342 / 902

Advancing to step 4:
902 goes into 4342 4 times with a remainder of 734.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 3608 from 4342 leaves us with 734.
Fetch the next digit (0) from the dividend, attach it to 734 and continue: 7340 / 902

Going ahead to step 5:
If we divide 7340 by 902, we get 8 and a remainder of 124.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we subtract 7216 from 7340, we get 124.
Include the next digit (5) from the dividend after 124, then repeat: 1245 / 902

Let's proceed to step 6:
When dividing 1245 by 902, we get 1 with a remainder of 343.
The next digit of our result is 1. 
Result so far: 481.0
If we subtract 902 from 1245, we get 343.
Append the next digit (2) from the dividend to 343 and continue with: 3432 / 902

Let's proceed to step 7:
3432 divided by 902 is 3 with a remainder of 726.
The number 3 becomes the next digit in our result. 
Result so far: 4813.0
If we subtract 2706 from 3432, we get 726.
Include the next digit (6) from the dividend after 726, then repeat: 7266 / 902

Step 8:
The number 902 fits into 7266 8 times, leaving a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 48138.0
If we subtract 7216 from 7266, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
When dividing 500 by 902, we get 0 with a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 48138.0
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 10:
The number 902 fits into 5000 5 times, leaving a remainder of 490.
Put 5 as the next digit of the answer. 
Result so far: 48138.05
Deduct 4510 from 5000 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 11:
902 can be fit into 4900 5 times, resulting in a remainder of 390.
Record the quotient 5 as the next digit in the result. 
Result so far: 48138.055
Subtracting 4510 from 4900 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

In conclusion, the division gives 48138.055 with a balance of 0.039.
