We divide 78854498 by 420
The aim is to understand the frequency of 420 in 78854498.

Advancing to step 1:
The number 420 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 420

Going ahead to step 2:
420 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (8) from the dividend after 78, then repeat: 788 / 420

Moving on to step 3:
When dividing 788 by 420, we get 1 with a remainder of 368.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 368 after subtracting 420 from 788.
Fetch the next digit (5) from the dividend, attach it to 368 and continue: 3685 / 420

Let's proceed to step 4:
420 goes into 3685 8 times with a remainder of 325.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 3360 from 3685 leaves us with 325.
Include the next digit (4) from the dividend after 325, then repeat: 3254 / 420

On to step 5:
The number 420 fits into 3254 7 times, leaving a remainder of 314.
Write down 7 as next digit of the result. 
Result so far: 187.0
If we subtract 2940 from 3254, we get 314.
Take the next digit (4) from the dividend and append it to 314, then repeat: 3144 / 420

Step 6:
When dividing 3144 by 420, we get 7 with a remainder of 204.
The number 7 becomes the next digit in our result. 
Result so far: 1877.0
If we take 2940 away from 3144, we end up with 204.
Fetch the next digit (9) from the dividend, attach it to 204 and continue: 2049 / 420

Let's proceed to step 7:
If we divide 2049 by 420, we get 4 and a remainder of 369.
Put 4 as the next digit of the answer. 
Result so far: 18774.0
Subtract 1680 from 2049 to get 369.
Grab the next digit (8) from the dividend, add it to 369, then carry on: 3698 / 420

Moving on to step 8:
The number 420 fits into 3698 8 times, leaving a remainder of 338.
Record the quotient 8 as the next digit in the result. 
Result so far: 187748.0
Subtract 3360 from 3698 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 9:
3380 divided by 420 is 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 187748.8
Subtract 3360 from 3380 to get 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:
200 divided by 420 is 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 187748.8
The remainder is 200 after subtracting 0 from 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 11:
If we divide 2000 by 420, we get 4 and a remainder of 320.
The next digit of our result is 4. 
Result so far: 187748.804
Subtract 1680 from 2000 to 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 12:
420 goes into 3200 7 times with a remainder of 260.
Write down 7 as next digit of the result. 
Result so far: 187748.8047
Subtracting 2940 from 3200 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 13:
When dividing 2600 by 420, we get 6 with a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 187748.80476
If we subtract 2520 from 2600, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
420 can be fit into 800 1 times, resulting in a remainder of 380.
Record the quotient 1 as the next digit in the result. 
Result so far: 187748.804761
Subtract 420 from 800 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 15:
When dividing 3800 by 420, we get 9 with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 187748.8047619
The remainder is 20 after subtracting 3780 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 16:
200 divided by 420 is 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 187748.8047619
Subtract 0 from 200 to 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.

The quotient of the division is 187748.8047619, and the remainder is 2e-07.
