720987 ÷ 46 
The aim is to understand the frequency of 46 in 720987.

On to step 1:
If we divide 7 by 46, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 46

Moving on to step 2:
72 divided by 46 is 1 with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 26 after subtracting 46 from 72.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 46

Step 3:
If we divide 260 by 46, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 30 after subtracting 230 from 260.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 46

Advancing to step 4:
The number 46 fits into 309 6 times, leaving a remainder of 33.
Put 6 as the next digit of the answer. 
Result so far: 156.0
Subtract 276 from 309 to get 33.
Grab the next digit (8) from the dividend, add it to 33, then carry on: 338 / 46

Moving on to step 5:
The number 46 fits into 338 7 times, leaving a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 1567.0
If we take 322 away from 338, we end up with 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 46

Moving on to step 6:
If we divide 167 by 46, we get 3 and a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 15673.0
Deduct 138 from 167 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
46 goes into 290 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 15673.6
The remainder is 14 after subtracting 276 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
140 divided by 46 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 15673.63
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
If we divide 20 by 46, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 15673.63
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
When dividing 200 by 46, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 15673.6304
Subtracting 184 from 200 leaves us with 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 11:
160 divided by 46 is 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 15673.63043
Deduct 138 from 160 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
The number 46 fits into 220 4 times, leaving a remainder of 36.
The next digit of our result is 4. 
Result so far: 15673.630434
Deduct 184 from 220 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
If we divide 360 by 46, we get 7 and a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 15673.6304347
Deduct 322 from 360 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
If we divide 380 by 46, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 15673.63043478
Subtract 368 from 380 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 15673.63043478 and a remainder of 1.2e-08.
