Let's divide 98235547 by 642
The aim is to understand the frequency of 642 in 98235547.

Advancing to step 1:
If we divide 9 by 642, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 642

Moving on to step 2:
642 can be fit into 98 0 times, resulting in a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Include the next digit (2) from the dividend after 98, then repeat: 982 / 642

Advancing to step 3:
642 can be fit into 982 1 times, resulting in a remainder of 340.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 642 from 982 and we're left with 340.
Append the next digit (3) from the dividend to 340 and continue with: 3403 / 642

Advancing to step 4:
The number 642 fits into 3403 5 times, leaving a remainder of 193.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 3210 from 3403 and we're left with 193.
Fetch the next digit (5) from the dividend, attach it to 193 and continue: 1935 / 642

Moving on to step 5:
1935 divided by 642 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
Subtract 1926 from 1935 to get 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 642

On to step 6:
If we divide 95 by 642, we get 0 and a remainder of 95.
Put 0 as the next digit of the answer. 
Result so far: 1530.0
Subtracting 0 from 95 leaves us with 95.
Append the next digit (4) from the dividend to 95 and continue with: 954 / 642

Let's proceed to step 7:
642 can be fit into 954 1 times, resulting in a remainder of 312.
The number 1 becomes the next digit in our result. 
Result so far: 15301.0
If we take 642 away from 954, we end up with 312.
Include the next digit (7) from the dividend after 312, then repeat: 3127 / 642

Step 8:
The number 642 fits into 3127 4 times, leaving a remainder of 559.
The number 4 becomes the next digit in our result. 
Result so far: 153014.0
Subtracting 2568 from 3127 leaves us with 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Step 9:
5590 divided by 642 is 8 with a remainder of 454.
Write down 8 as next digit of the result. 
Result so far: 153014.8
Deduct 5136 from 5590 and we're left with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Let's proceed to step 10:
4540 divided by 642 is 7 with a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 153014.87
The remainder is 46 after subtracting 4494 from 4540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
The number 642 fits into 460 0 times, leaving a remainder of 460.
The number 0 becomes the next digit in our result. 
Result so far: 153014.87
Subtract 0 from 460 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 12:
642 goes into 4600 7 times with a remainder of 106.
Use 7 as the next digit of our solution. 
Result so far: 153014.8707
Subtracting 4494 from 4600 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 13:
642 goes into 1060 1 times with a remainder of 418.
The number 1 becomes the next digit in our result. 
Result so far: 153014.87071
If we take 642 away from 1060, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 14:
642 can be fit into 4180 6 times, resulting in a remainder of 328.
Write down 6 as next digit of the result. 
Result so far: 153014.870716
If we take 3852 away from 4180, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 15:
The number 642 fits into 3280 5 times, leaving a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 153014.8707165
The remainder is 70 after subtracting 3210 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 16:
642 goes into 700 1 times with a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 153014.87071651
Deduct 642 from 700 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 153014.87071651, with a leftover of 5.8e-08.
