We're dividing 86415143 by 948 
The aim is to understand the frequency of 948 in 86415143.

Let's proceed to step 1:
948 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 948

On to step 2:
The number 948 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 948

Step 3:
The number 948 fits into 864 0 times, leaving a remainder of 864.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 864 and we're left with 864.
Fetch the next digit (1) from the dividend, attach it to 864 and continue: 8641 / 948

Advancing to step 4:
948 goes into 8641 9 times with a remainder of 109.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 8532 from 8641, we get 109.
Append the next digit (5) from the dividend to 109 and continue with: 1095 / 948

Advancing to step 5:
948 goes into 1095 1 times with a remainder of 147.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
If we subtract 948 from 1095, we get 147.
Append the next digit (1) from the dividend to 147 and continue with: 1471 / 948

Advancing to step 6:
When dividing 1471 by 948, we get 1 with a remainder of 523.
The next digit of our result is 1. 
Result so far: 911.0
If we take 948 away from 1471, we end up with 523.
Fetch the next digit (4) from the dividend, attach it to 523 and continue: 5234 / 948

Going ahead to step 7:
5234 divided by 948 is 5 with a remainder of 494.
The number 5 becomes the next digit in our result. 
Result so far: 9115.0
If we subtract 4740 from 5234, we get 494.
Include the next digit (3) from the dividend after 494, then repeat: 4943 / 948

Step 8:
948 goes into 4943 5 times with a remainder of 203.
The next digit of our result is 5. 
Result so far: 91155.0
If we subtract 4740 from 4943, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 9:
When dividing 2030 by 948, we get 2 with a remainder of 134.
Put 2 as the next digit of the answer. 
Result so far: 91155.2
Subtract 1896 from 2030 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 10:
948 can be fit into 1340 1 times, resulting in a remainder of 392.
Use 1 as the next digit of our solution. 
Result so far: 91155.21
The remainder is 392 after subtracting 948 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 11:
948 goes into 3920 4 times with a remainder of 128.
The number 4 becomes the next digit in our result. 
Result so far: 91155.214
If we take 3792 away from 3920, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 12:
1280 divided by 948 is 1 with a remainder of 332.
The number 1 becomes the next digit in our result. 
Result so far: 91155.2141
Deduct 948 from 1280 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 13:
If we divide 3320 by 948, we get 3 and a remainder of 476.
The number 3 becomes the next digit in our result. 
Result so far: 91155.21413
Subtract 2844 from 3320 to get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 14:
948 goes into 4760 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 91155.214135
Subtract 4740 from 4760 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 15:
948 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 91155.214135
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 16:
If we divide 2000 by 948, we get 2 and a remainder of 104.
Write down 2 as next digit of the result. 
Result so far: 91155.21413502
If we subtract 1896 from 2000, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Our division results in 91155.21413502 with a remaining 1.04e-07.
