We're dividing 78710822 by 840 
The aim is to understand the frequency of 840 in 78710822.

Moving on to step 1:
840 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 840

Let's proceed to step 2:
840 goes into 78 0 times with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 840

Let's proceed to step 3:
840 can be fit into 787 0 times, resulting in a remainder of 787.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 787 and we're left with 787.
Take the next digit (1) from the dividend and append it to 787, then repeat: 7871 / 840

Moving on to step 4:
840 can be fit into 7871 9 times, resulting in a remainder of 311.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 311 after subtracting 7560 from 7871.
Grab the next digit (0) from the dividend, add it to 311, then carry on: 3110 / 840

Going ahead to step 5:
840 can be fit into 3110 3 times, resulting in a remainder of 590.
The next digit of our result is 3. 
Result so far: 93.0
Subtracting 2520 from 3110 leaves us with 590.
Append the next digit (8) from the dividend to 590 and continue with: 5908 / 840

Step 6:
If we divide 5908 by 840, we get 7 and a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 937.0
Subtract 5880 from 5908 to get 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 840

Advancing to step 7:
The number 840 fits into 282 0 times, leaving a remainder of 282.
Write down 0 as next digit of the result. 
Result so far: 9370.0
Subtract 0 from 282 to get 282.
Append the next digit (2) from the dividend to 282 and continue with: 2822 / 840

Moving on to step 8:
840 goes into 2822 3 times with a remainder of 302.
Record the quotient 3 as the next digit in the result. 
Result so far: 93703.0
If we subtract 2520 from 2822, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 9:
The number 840 fits into 3020 3 times, leaving a remainder of 500.
The number 3 becomes the next digit in our result. 
Result so far: 93703.3
If we subtract 2520 from 3020, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 10:
If we divide 5000 by 840, we get 5 and a remainder of 800.
The next digit of our result is 5. 
Result so far: 93703.35
Subtract 4200 from 5000 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Let's proceed to step 11:
If we divide 8000 by 840, we get 9 and a remainder of 440.
The next digit of our result is 9. 
Result so far: 93703.359
If we subtract 7560 from 8000, we 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.

Going ahead to step 12:
840 goes into 4400 5 times with a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 93703.3595
If we subtract 4200 from 4400, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 13:
2000 divided by 840 is 2 with a remainder of 320.
Write down 2 as next digit of the result. 
Result so far: 93703.35952
If we subtract 1680 from 2000, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 14:
If we divide 3200 by 840, we get 3 and a remainder of 680.
The number 3 becomes the next digit in our result. 
Result so far: 93703.359523
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.

Step 15:
When dividing 6800 by 840, we get 8 with a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 93703.3595238
Subtracting 6720 from 6800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 16:
840 can be fit into 800 0 times, resulting in a remainder of 800.
The next digit of our result is 0. 
Result so far: 93703.3595238
If we subtract 0 from 800, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final outcome is 93703.3595238, with a leftover of 8e-07.
