49409507 ÷ 642 
The aim is to understand the frequency of 642 in 49409507.

On to step 1:
The number 642 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 642

Going ahead to step 2:
49 divided by 642 is 0 with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Fetch the next digit (4) from the dividend, attach it to 49 and continue: 494 / 642

On to step 3:
When dividing 494 by 642, we get 0 with a remainder of 494.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 494 leaves us with 494.
Append the next digit (0) from the dividend to 494 and continue with: 4940 / 642

Moving on to step 4:
4940 divided by 642 is 7 with a remainder of 446.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 4494 from 4940 leaves us with 446.
Include the next digit (9) from the dividend after 446, then repeat: 4469 / 642

Going ahead to step 5:
The number 642 fits into 4469 6 times, leaving a remainder of 617.
The next digit of our result is 6. 
Result so far: 76.0
If we subtract 3852 from 4469, we get 617.
Bring next digit (5) of the dividend behind the 617 and repeat the process: 6175 / 642

Going ahead to step 6:
If we divide 6175 by 642, we get 9 and a remainder of 397.
Put 9 as the next digit of the answer. 
Result so far: 769.0
The remainder is 397 after subtracting 5778 from 6175.
Bring next digit (0) of the dividend behind the 397 and repeat the process: 3970 / 642

Advancing to step 7:
When dividing 3970 by 642, we get 6 with a remainder of 118.
The next digit of our result is 6. 
Result so far: 7696.0
The remainder is 118 after subtracting 3852 from 3970.
Include the next digit (7) from the dividend after 118, then repeat: 1187 / 642

Step 8:
If we divide 1187 by 642, we get 1 and a remainder of 545.
Use 1 as the next digit of our solution. 
Result so far: 76961.0
If we take 642 away from 1187, we end up with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Advancing to step 9:
The number 642 fits into 5450 8 times, leaving a remainder of 314.
The next digit of our result is 8. 
Result so far: 76961.8
Subtract 5136 from 5450 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Let's proceed to step 10:
The number 642 fits into 3140 4 times, leaving a remainder of 572.
Use 4 as the next digit of our solution. 
Result so far: 76961.84
Deduct 2568 from 3140 and we're left with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Moving on to step 11:
If we divide 5720 by 642, we get 8 and a remainder of 584.
Record the quotient 8 as the next digit in the result. 
Result so far: 76961.848
Deduct 5136 from 5720 and we're left with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 12:
When dividing 5840 by 642, we get 9 with a remainder of 62.
The next digit of our result is 9. 
Result so far: 76961.8489
Subtract 5778 from 5840 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 13:
642 goes into 620 0 times with a remainder of 620.
The next digit of our result is 0. 
Result so far: 76961.8489
If we take 0 away from 620, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 14:
If we divide 6200 by 642, we get 9 and a remainder of 422.
Write down 9 as next digit of the result. 
Result so far: 76961.848909
The remainder is 422 after subtracting 5778 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Going ahead to step 15:
When dividing 4220 by 642, we get 6 with a remainder of 368.
The next digit of our result is 6. 
Result so far: 76961.8489096
If we subtract 3852 from 4220, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 16:
3680 divided by 642 is 5 with a remainder of 470.
Record the quotient 5 as the next digit in the result. 
Result so far: 76961.84890965
Subtract 3210 from 3680 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

The final result is 76961.84890965 with a remainder of 4.7e-07.
