We divide 97451740 by 642
The aim is to understand the frequency of 642 in 97451740.

Advancing to step 1:
When dividing 9 by 642, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 642

Going ahead to step 2:
When dividing 97 by 642, we get 0 with a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 97 and we're left with 97.
Include the next digit (4) from the dividend after 97, then repeat: 974 / 642

Moving on to step 3:
When dividing 974 by 642, we get 1 with a remainder of 332.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 642 from 974 and we're left with 332.
Take the next digit (5) from the dividend and append it to 332, then repeat: 3325 / 642

Let's proceed to step 4:
3325 divided by 642 is 5 with a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 3210 from 3325 and we're left with 115.
Append the next digit (1) from the dividend to 115 and continue with: 1151 / 642

Moving on to step 5:
If we divide 1151 by 642, we get 1 and a remainder of 509.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
The remainder is 509 after subtracting 642 from 1151.
Fetch the next digit (7) from the dividend, attach it to 509 and continue: 5097 / 642

Step 6:
642 can be fit into 5097 7 times, resulting in a remainder of 603.
Put 7 as the next digit of the answer. 
Result so far: 1517.0
If we take 4494 away from 5097, we end up with 603.
Bring next digit (4) of the dividend behind the 603 and repeat the process: 6034 / 642

Step 7:
If we divide 6034 by 642, we get 9 and a remainder of 256.
The next digit of our result is 9. 
Result so far: 15179.0
If we subtract 5778 from 6034, we get 256.
Take the next digit (0) from the dividend and append it to 256, then repeat: 2560 / 642

Advancing to step 8:
642 can be fit into 2560 3 times, resulting in a remainder of 634.
The number 3 becomes the next digit in our result. 
Result so far: 151793.0
If we subtract 1926 from 2560, we get 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Let's proceed to step 9:
If we divide 6340 by 642, we get 9 and a remainder of 562.
Use 9 as the next digit of our solution. 
Result so far: 151793.9
The remainder is 562 after subtracting 5778 from 6340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Moving on to step 10:
When dividing 5620 by 642, we get 8 with a remainder of 484.
Write down 8 as next digit of the result. 
Result so far: 151793.98
Subtracting 5136 from 5620 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Step 11:
4840 divided by 642 is 7 with a remainder of 346.
Write down 7 as next digit of the result. 
Result so far: 151793.987
Deduct 4494 from 4840 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Moving on to step 12:
642 can be fit into 3460 5 times, resulting in a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 151793.9875
If we take 3210 away from 3460, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 13:
642 can be fit into 2500 3 times, resulting in a remainder of 574.
The number 3 becomes the next digit in our result. 
Result so far: 151793.98753
If we subtract 1926 from 2500, we get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

On to step 14:
The number 642 fits into 5740 8 times, leaving a remainder of 604.
The next digit of our result is 8. 
Result so far: 151793.987538
If we subtract 5136 from 5740, we get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Moving on to step 15:
6040 divided by 642 is 9 with a remainder of 262.
Record the quotient 9 as the next digit in the result. 
Result so far: 151793.9875389
Deduct 5778 from 6040 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 16:
2620 divided by 642 is 4 with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 151793.98753894
If we take 2568 away from 2620, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 151793.98753894 with a balance of 5.2e-08.
