6935344 ÷ 840 
The aim is to understand the frequency of 840 in 6935344.

Moving on to step 1:
The number 840 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 840

Going ahead to step 2:
840 goes into 69 0 times with a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Grab the next digit (3) from the dividend, add it to 69, then carry on: 693 / 840

On to step 3:
693 divided by 840 is 0 with a remainder of 693.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 693, we get 693.
Fetch the next digit (5) from the dividend, attach it to 693 and continue: 6935 / 840

Going ahead to step 4:
840 goes into 6935 8 times with a remainder of 215.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 6720 from 6935 and we're left with 215.
Append the next digit (3) from the dividend to 215 and continue with: 2153 / 840

Let's proceed to step 5:
840 goes into 2153 2 times with a remainder of 473.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Subtract 1680 from 2153 to get 473.
Include the next digit (4) from the dividend after 473, then repeat: 4734 / 840

Let's proceed to step 6:
840 goes into 4734 5 times with a remainder of 534.
Record the quotient 5 as the next digit in the result. 
Result so far: 825.0
Subtract 4200 from 4734 to get 534.
Append the next digit (4) from the dividend to 534 and continue with: 5344 / 840

Step 7:
The number 840 fits into 5344 6 times, leaving a remainder of 304.
The next digit of our result is 6. 
Result so far: 8256.0
If we subtract 5040 from 5344, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 8:
The number 840 fits into 3040 3 times, leaving a remainder of 520.
Write down 3 as next digit of the result. 
Result so far: 8256.3
If we subtract 2520 from 3040, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 9:
When dividing 5200 by 840, we get 6 with a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 8256.36
If we take 5040 away from 5200, we end up 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.

On to step 10:
If we divide 1600 by 840, we get 1 and a remainder of 760.
Use 1 as the next digit of our solution. 
Result so far: 8256.361
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.

Advancing to step 11:
When dividing 7600 by 840, we get 9 with a remainder of 40.
The next digit of our result is 9. 
Result so far: 8256.3619
Subtracting 7560 from 7600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

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: 8256.3619
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 13:
840 goes into 4000 4 times with a remainder of 640.
The number 4 becomes the next digit in our result. 
Result so far: 8256.361904
Deduct 3360 from 4000 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 14:
When dividing 6400 by 840, we get 7 with a remainder of 520.
The number 7 becomes the next digit in our result. 
Result so far: 8256.3619047
Subtract 5880 from 6400 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 15:
5200 divided by 840 is 6 with a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 8256.36190476
Subtracting 5040 from 5200 leaves us 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.

After the division, we end up with 8256.36190476 and a remainder of 1.6e-07.
