We're dividing 83543865 by 948 
The aim is to understand the frequency of 948 in 83543865.

Going ahead to step 1:
When dividing 8 by 948, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 948

Let's proceed to step 2:
948 can be fit into 83 0 times, resulting in a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Fetch the next digit (5) from the dividend, attach it to 83 and continue: 835 / 948

On to step 3:
948 goes into 835 0 times with a remainder of 835.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 835, we get 835.
Append the next digit (4) from the dividend to 835 and continue with: 8354 / 948

Let's proceed to step 4:
The number 948 fits into 8354 8 times, leaving a remainder of 770.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 7584 away from 8354, we end up with 770.
Take the next digit (3) from the dividend and append it to 770, then repeat: 7703 / 948

Let's proceed to step 5:
948 can be fit into 7703 8 times, resulting in a remainder of 119.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
Deduct 7584 from 7703 and we're left with 119.
Grab the next digit (8) from the dividend, add it to 119, then carry on: 1198 / 948

Advancing to step 6:
The number 948 fits into 1198 1 times, leaving a remainder of 250.
Use 1 as the next digit of our solution. 
Result so far: 881.0
If we subtract 948 from 1198, we get 250.
Grab the next digit (6) from the dividend, add it to 250, then carry on: 2506 / 948

On to step 7:
The number 948 fits into 2506 2 times, leaving a remainder of 610.
The next digit of our result is 2. 
Result so far: 8812.0
Subtracting 1896 from 2506 leaves us with 610.
Include the next digit (5) from the dividend after 610, then repeat: 6105 / 948

Going ahead to step 8:
6105 divided by 948 is 6 with a remainder of 417.
Use 6 as the next digit of our solution. 
Result so far: 88126.0
Subtract 5688 from 6105 to get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Let's proceed to step 9:
If we divide 4170 by 948, we get 4 and a remainder of 378.
Use 4 as the next digit of our solution. 
Result so far: 88126.4
The remainder is 378 after subtracting 3792 from 4170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Moving on to step 10:
If we divide 3780 by 948, we get 3 and a remainder of 936.
Put 3 as the next digit of the answer. 
Result so far: 88126.43
If we take 2844 away from 3780, we end up with 936.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9360, and continue the process.

Going ahead to step 11:
If we divide 9360 by 948, we get 9 and a remainder of 828.
Put 9 as the next digit of the answer. 
Result so far: 88126.439
Subtracting 8532 from 9360 leaves us with 828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

Step 12:
8280 divided by 948 is 8 with a remainder of 696.
Put 8 as the next digit of the answer. 
Result so far: 88126.4398
Deduct 7584 from 8280 and we're left with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Let's proceed to step 13:
948 goes into 6960 7 times with a remainder of 324.
Use 7 as the next digit of our solution. 
Result so far: 88126.43987
The remainder is 324 after subtracting 6636 from 6960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 14:
When dividing 3240 by 948, we get 3 with a remainder of 396.
Write down 3 as next digit of the result. 
Result so far: 88126.439873
If we subtract 2844 from 3240, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 15:
948 goes into 3960 4 times with a remainder of 168.
The number 4 becomes the next digit in our result. 
Result so far: 88126.4398734
Subtracting 3792 from 3960 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 16:
If we divide 1680 by 948, we get 1 and a remainder of 732.
Record the quotient 1 as the next digit in the result. 
Result so far: 88126.43987341
The remainder is 732 after subtracting 948 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

The final outcome is 88126.43987341, with a leftover of 7.32e-07.
