Let's divide 30618491 by 840
The aim is to understand the frequency of 840 in 30618491.

Going ahead to step 1:
If we divide 3 by 840, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 840

Step 2:
840 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 840

Moving on to step 3:
The number 840 fits into 306 0 times, leaving a remainder of 306.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 306 after subtracting 0 from 306.
Append the next digit (1) from the dividend to 306 and continue with: 3061 / 840

Let's proceed to step 4:
When dividing 3061 by 840, we get 3 with a remainder of 541.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 2520 from 3061 and we're left with 541.
Fetch the next digit (8) from the dividend, attach it to 541 and continue: 5418 / 840

Let's proceed to step 5:
5418 divided by 840 is 6 with a remainder of 378.
The next digit of our result is 6. 
Result so far: 36.0
If we take 5040 away from 5418, we end up with 378.
Include the next digit (4) from the dividend after 378, then repeat: 3784 / 840

Moving on to step 6:
3784 divided by 840 is 4 with a remainder of 424.
Write down 4 as next digit of the result. 
Result so far: 364.0
Subtract 3360 from 3784 to get 424.
Grab the next digit (9) from the dividend, add it to 424, then carry on: 4249 / 840

Advancing to step 7:
4249 divided by 840 is 5 with a remainder of 49.
Use 5 as the next digit of our solution. 
Result so far: 3645.0
If we take 4200 away from 4249, we end up with 49.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 840

Going ahead to step 8:
When dividing 491 by 840, we get 0 with a remainder of 491.
The next digit of our result is 0. 
Result so far: 36450.0
Subtract 0 from 491 to get 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Step 9:
The number 840 fits into 4910 5 times, leaving a remainder of 710.
Record the quotient 5 as the next digit in the result. 
Result so far: 36450.5
Subtract 4200 from 4910 to get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Moving on to step 10:
7100 divided by 840 is 8 with a remainder of 380.
The next digit of our result is 8. 
Result so far: 36450.58
If we take 6720 away from 7100, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 11:
If we divide 3800 by 840, we get 4 and a remainder of 440.
The next digit of our result is 4. 
Result so far: 36450.584
Subtract 3360 from 3800 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 12:
840 can be fit into 4400 5 times, resulting in a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 36450.5845
Deduct 4200 from 4400 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 13:
840 goes into 2000 2 times with a remainder of 320.
Put 2 as the next digit of the answer. 
Result so far: 36450.58452
Deduct 1680 from 2000 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 14:
840 goes into 3200 3 times with a remainder of 680.
Write down 3 as next digit of the result. 
Result so far: 36450.584523
Deduct 2520 from 3200 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 15:
840 goes into 6800 8 times with a remainder of 80.
The next digit of our result is 8. 
Result so far: 36450.5845238
The remainder is 80 after subtracting 6720 from 6800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 16:
If we divide 800 by 840, we get 0 and a remainder of 800.
Use 0 as the next digit of our solution. 
Result so far: 36450.5845238
Deduct 0 from 800 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

In conclusion, the division gives 36450.5845238 with a balance of 8e-07.
