Let's divide 19642114 by 840
The aim is to understand the frequency of 840 in 19642114.

Advancing to step 1:
If we divide 1 by 840, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 840

Step 2:
19 divided by 840 is 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 840

Let's proceed to step 3:
196 divided by 840 is 0 with a remainder of 196.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 196, we end up with 196.
Bring next digit (4) of the dividend behind the 196 and repeat the process: 1964 / 840

Advancing to step 4:
If we divide 1964 by 840, we get 2 and a remainder of 284.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 284 after subtracting 1680 from 1964.
Bring next digit (2) of the dividend behind the 284 and repeat the process: 2842 / 840

Let's proceed to step 5:
The number 840 fits into 2842 3 times, leaving a remainder of 322.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 322 after subtracting 2520 from 2842.
Fetch the next digit (1) from the dividend, attach it to 322 and continue: 3221 / 840

Moving on to step 6:
3221 divided by 840 is 3 with a remainder of 701.
Record the quotient 3 as the next digit in the result. 
Result so far: 233.0
Subtract 2520 from 3221 to get 701.
Include the next digit (1) from the dividend after 701, then repeat: 7011 / 840

Let's proceed to step 7:
If we divide 7011 by 840, we get 8 and a remainder of 291.
Write down 8 as next digit of the result. 
Result so far: 2338.0
If we subtract 6720 from 7011, we get 291.
Fetch the next digit (4) from the dividend, attach it to 291 and continue: 2914 / 840

Let's proceed to step 8:
When dividing 2914 by 840, we get 3 with a remainder of 394.
Put 3 as the next digit of the answer. 
Result so far: 23383.0
Subtract 2520 from 2914 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Advancing to step 9:
840 goes into 3940 4 times with a remainder of 580.
Record the quotient 4 as the next digit in the result. 
Result so far: 23383.4
Deduct 3360 from 3940 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 10:
If we divide 5800 by 840, we get 6 and a remainder of 760.
The number 6 becomes the next digit in our result. 
Result so far: 23383.46
If we subtract 5040 from 5800, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Step 11:
7600 divided by 840 is 9 with a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 23383.469
If we subtract 7560 from 7600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
When dividing 400 by 840, we get 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 23383.469
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
The number 840 fits into 4000 4 times, leaving a remainder of 640.
Write down 4 as next digit of the result. 
Result so far: 23383.46904
If we subtract 3360 from 4000, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 14:
If we divide 6400 by 840, we get 7 and a remainder of 520.
The number 7 becomes the next digit in our result. 
Result so far: 23383.469047
Subtracting 5880 from 6400 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 15:
If we divide 5200 by 840, we get 6 and a remainder of 160.
Record the quotient 6 as the next digit in the result. 
Result so far: 23383.4690476
Deduct 5040 from 5200 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 16:
The number 840 fits into 1600 1 times, leaving a remainder of 760.
The number 1 becomes the next digit in our result. 
Result so far: 23383.46904761
If we subtract 840 from 1600, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

After the division, we end up with 23383.46904761 and a remainder of 7.6e-07.
