We divide 83285412 by 420
The aim is to understand the frequency of 420 in 83285412.

Step 1:
The number 420 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 420

Advancing to step 2:
83 divided by 420 is 0 with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Bring next digit (2) of the dividend behind the 83 and repeat the process: 832 / 420

Let's proceed to step 3:
When dividing 832 by 420, we get 1 with a remainder of 412.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 420 from 832 to get 412.
Grab the next digit (8) from the dividend, add it to 412, then carry on: 4128 / 420

Moving on to step 4:
4128 divided by 420 is 9 with a remainder of 348.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 3780 from 4128, we get 348.
Fetch the next digit (5) from the dividend, attach it to 348 and continue: 3485 / 420

On to step 5:
420 can be fit into 3485 8 times, resulting in a remainder of 125.
The number 8 becomes the next digit in our result. 
Result so far: 198.0
Deduct 3360 from 3485 and we're left with 125.
Take the next digit (4) from the dividend and append it to 125, then repeat: 1254 / 420

Moving on to step 6:
420 can be fit into 1254 2 times, resulting in a remainder of 414.
Use 2 as the next digit of our solution. 
Result so far: 1982.0
Subtracting 840 from 1254 leaves us with 414.
Grab the next digit (1) from the dividend, add it to 414, then carry on: 4141 / 420

Going ahead to step 7:
If we divide 4141 by 420, we get 9 and a remainder of 361.
Record the quotient 9 as the next digit in the result. 
Result so far: 19829.0
Deduct 3780 from 4141 and we're left with 361.
Grab the next digit (2) from the dividend, add it to 361, then carry on: 3612 / 420

Step 8:
The number 420 fits into 3612 8 times, leaving a remainder of 252.
Write down 8 as next digit of the result. 
Result so far: 198298.0
If we take 3360 away from 3612, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 9:
When dividing 2520 by 420, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 198298.6
Subtracting 2520 from 2520 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
When dividing 0 by 420, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 198298.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
If we divide 0 by 420, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 198298.6
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 198298.6, with a leftover of 0.0.
