842143 ÷ 83 
The aim is to understand the frequency of 83 in 842143.

Going ahead to step 1:
83 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 83

On to step 2:
When dividing 84 by 83, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 83 from 84 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 83

Moving on to step 3:
83 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 83

Going ahead to step 4:
83 can be fit into 121 1 times, resulting in a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 101.0
The remainder is 38 after subtracting 83 from 121.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 83

On to step 5:
If we divide 384 by 83, we get 4 and a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 1014.0
The remainder is 52 after subtracting 332 from 384.
Bring next digit (3) of the dividend behind the 52 and repeat the process: 523 / 83

Step 6:
If we divide 523 by 83, we get 6 and a remainder of 25.
Put 6 as the next digit of the answer. 
Result so far: 10146.0
Subtract 498 from 523 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
83 goes into 250 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 10146.3
Subtract 249 from 250 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
83 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 10146.3
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
The number 83 fits into 100 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 10146.301
The remainder is 17 after subtracting 83 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 10:
83 goes into 170 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 10146.3012
Deduct 166 from 170 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
83 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10146.3012
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
83 goes into 400 4 times with a remainder of 68.
The next digit of our result is 4. 
Result so far: 10146.301204
Deduct 332 from 400 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 13:
83 goes into 680 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 10146.3012048
If we subtract 664 from 680, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
If we divide 160 by 83, we get 1 and a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 10146.30120481
Deduct 83 from 160 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The quotient of the division is 10146.30120481, and the remainder is 7.7e-08.
