We're dividing 38613970 by 435 
The aim is to understand the frequency of 435 in 38613970.

Step 1:
3 divided by 435 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 435

Moving on to step 2:
38 divided by 435 is 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 435

Going ahead to step 3:
When dividing 386 by 435, we get 0 with a remainder of 386.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 386, we get 386.
Grab the next digit (1) from the dividend, add it to 386, then carry on: 3861 / 435

Going ahead to step 4:
The number 435 fits into 3861 8 times, leaving a remainder of 381.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 3480 from 3861, we get 381.
Include the next digit (3) from the dividend after 381, then repeat: 3813 / 435

Going ahead to step 5:
3813 divided by 435 is 8 with a remainder of 333.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
If we take 3480 away from 3813, we end up with 333.
Append the next digit (9) from the dividend to 333 and continue with: 3339 / 435

Moving on to step 6:
If we divide 3339 by 435, we get 7 and a remainder of 294.
The number 7 becomes the next digit in our result. 
Result so far: 887.0
If we subtract 3045 from 3339, we get 294.
Grab the next digit (7) from the dividend, add it to 294, then carry on: 2947 / 435

Going ahead to step 7:
435 goes into 2947 6 times with a remainder of 337.
Put 6 as the next digit of the answer. 
Result so far: 8876.0
The remainder is 337 after subtracting 2610 from 2947.
Bring next digit (0) of the dividend behind the 337 and repeat the process: 3370 / 435

Advancing to step 8:
3370 divided by 435 is 7 with a remainder of 325.
Put 7 as the next digit of the answer. 
Result so far: 88767.0
The remainder is 325 after subtracting 3045 from 3370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 9:
3250 divided by 435 is 7 with a remainder of 205.
Record the quotient 7 as the next digit in the result. 
Result so far: 88767.7
The remainder is 205 after subtracting 3045 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 10:
When dividing 2050 by 435, we get 4 with a remainder of 310.
Record the quotient 4 as the next digit in the result. 
Result so far: 88767.74
The remainder is 310 after subtracting 1740 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 11:
When dividing 3100 by 435, we get 7 with a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 88767.747
Deduct 3045 from 3100 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 12:
550 divided by 435 is 1 with a remainder of 115.
Record the quotient 1 as the next digit in the result. 
Result so far: 88767.7471
If we take 435 away from 550, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 13:
435 goes into 1150 2 times with a remainder of 280.
Record the quotient 2 as the next digit in the result. 
Result so far: 88767.74712
Subtracting 870 from 1150 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 14:
When dividing 2800 by 435, we get 6 with a remainder of 190.
Record the quotient 6 as the next digit in the result. 
Result so far: 88767.747126
Deduct 2610 from 2800 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 15:
The number 435 fits into 1900 4 times, leaving a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 88767.7471264
If we subtract 1740 from 1900, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 16:
When dividing 1600 by 435, we get 3 with a remainder of 295.
Write down 3 as next digit of the result. 
Result so far: 88767.74712643
If we subtract 1305 from 1600, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

In conclusion, the division gives 88767.74712643 with a balance of 2.95e-07.
