We're dividing 42038729 by 963 
The aim is to understand the frequency of 963 in 42038729.

Moving on to step 1:
963 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 963

Let's proceed to step 2:
963 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 963

Advancing to step 3:
963 can be fit into 420 0 times, resulting in a remainder of 420.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 420 leaves us with 420.
Include the next digit (3) from the dividend after 420, then repeat: 4203 / 963

On to step 4:
963 can be fit into 4203 4 times, resulting in a remainder of 351.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 3852 from 4203, we get 351.
Grab the next digit (8) from the dividend, add it to 351, then carry on: 3518 / 963

Step 5:
If we divide 3518 by 963, we get 3 and a remainder of 629.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we take 2889 away from 3518, we end up with 629.
Include the next digit (7) from the dividend after 629, then repeat: 6297 / 963

Moving on to step 6:
When dividing 6297 by 963, we get 6 with a remainder of 519.
Write down 6 as next digit of the result. 
Result so far: 436.0
Deduct 5778 from 6297 and we're left with 519.
Include the next digit (2) from the dividend after 519, then repeat: 5192 / 963

Going ahead to step 7:
5192 divided by 963 is 5 with a remainder of 377.
Use 5 as the next digit of our solution. 
Result so far: 4365.0
Subtracting 4815 from 5192 leaves us with 377.
Take the next digit (9) from the dividend and append it to 377, then repeat: 3779 / 963

Let's proceed to step 8:
If we divide 3779 by 963, we get 3 and a remainder of 890.
Write down 3 as next digit of the result. 
Result so far: 43653.0
If we take 2889 away from 3779, we end up with 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Moving on to step 9:
If we divide 8900 by 963, we get 9 and a remainder of 233.
The next digit of our result is 9. 
Result so far: 43653.9
Subtract 8667 from 8900 to get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 10:
If we divide 2330 by 963, we get 2 and a remainder of 404.
Write down 2 as next digit of the result. 
Result so far: 43653.92
Subtracting 1926 from 2330 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 11:
963 goes into 4040 4 times with a remainder of 188.
Write down 4 as next digit of the result. 
Result so far: 43653.924
The remainder is 188 after subtracting 3852 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 12:
1880 divided by 963 is 1 with a remainder of 917.
The next digit of our result is 1. 
Result so far: 43653.9241
If we subtract 963 from 1880, we get 917.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9170, and continue the process.

Going ahead to step 13:
9170 divided by 963 is 9 with a remainder of 503.
Write down 9 as next digit of the result. 
Result so far: 43653.92419
Deduct 8667 from 9170 and we're left with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Step 14:
963 can be fit into 5030 5 times, resulting in a remainder of 215.
Put 5 as the next digit of the answer. 
Result so far: 43653.924195
If we take 4815 away from 5030, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 15:
963 can be fit into 2150 2 times, resulting in a remainder of 224.
The number 2 becomes the next digit in our result. 
Result so far: 43653.9241952
If we subtract 1926 from 2150, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 16:
2240 divided by 963 is 2 with a remainder of 314.
Record the quotient 2 as the next digit in the result. 
Result so far: 43653.92419522
If we subtract 1926 from 2240, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

The final outcome is 43653.92419522, with a leftover of 3.14e-07.
