We divide 646739 by 74
The aim is to understand the frequency of 74 in 646739.

On to step 1:
74 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 74

Step 2:
64 divided by 74 is 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 74

Going ahead to step 3:
If we divide 646 by 74, we get 8 and a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 592 from 646 to get 54.
Grab the next digit (7) from the dividend, add it to 54, then carry on: 547 / 74

Going ahead to step 4:
74 goes into 547 7 times with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 87.0
Subtract 518 from 547 to get 29.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 74

Advancing to step 5:
When dividing 293 by 74, we get 3 with a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 873.0
The remainder is 71 after subtracting 222 from 293.
Take the next digit (9) from the dividend and append it to 71, then repeat: 719 / 74

Advancing to step 6:
The number 74 fits into 719 9 times, leaving a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 8739.0
The remainder is 53 after subtracting 666 from 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
When dividing 530 by 74, we get 7 with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 8739.7
Subtracting 518 from 530 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
When dividing 120 by 74, we get 1 with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 8739.71
If we subtract 74 from 120, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 9:
When dividing 460 by 74, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 8739.716
Subtract 444 from 460 to 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.

Advancing to step 10:
160 divided by 74 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 8739.7162
Deduct 148 from 160 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
The number 74 fits into 120 1 times, leaving a remainder of 46.
The next digit of our result is 1. 
Result so far: 8739.71621
If we subtract 74 from 120, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 12:
The number 74 fits into 460 6 times, leaving a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 8739.716216
Subtract 444 from 460 to 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 13:
74 goes into 160 2 times with a remainder of 12.
The next digit of our result is 2. 
Result so far: 8739.7162162
Deduct 148 from 160 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
When dividing 120 by 74, we get 1 with a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 8739.71621621
Subtract 74 from 120 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 8739.71621621 and a remainder of 4.6e-08.
