We divide 36436615 by 420
The aim is to understand the frequency of 420 in 36436615.

Let's proceed to step 1:
3 divided by 420 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 420

Going ahead to step 2:
When dividing 36 by 420, we get 0 with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 420

On to step 3:
420 goes into 364 0 times with a remainder of 364.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 364, we get 364.
Include the next digit (3) from the dividend after 364, then repeat: 3643 / 420

Going ahead to step 4:
420 goes into 3643 8 times with a remainder of 283.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 3360 from 3643 and we're left with 283.
Bring next digit (6) of the dividend behind the 283 and repeat the process: 2836 / 420

Going ahead to step 5:
420 goes into 2836 6 times with a remainder of 316.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
The remainder is 316 after subtracting 2520 from 2836.
Append the next digit (6) from the dividend to 316 and continue with: 3166 / 420

On to step 6:
420 goes into 3166 7 times with a remainder of 226.
Record the quotient 7 as the next digit in the result. 
Result so far: 867.0
Deduct 2940 from 3166 and we're left with 226.
Bring next digit (1) of the dividend behind the 226 and repeat the process: 2261 / 420

Moving on to step 7:
The number 420 fits into 2261 5 times, leaving a remainder of 161.
The number 5 becomes the next digit in our result. 
Result so far: 8675.0
Subtracting 2100 from 2261 leaves us with 161.
Include the next digit (5) from the dividend after 161, then repeat: 1615 / 420

On to step 8:
When dividing 1615 by 420, we get 3 with a remainder of 355.
The number 3 becomes the next digit in our result. 
Result so far: 86753.0
If we subtract 1260 from 1615, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Going ahead to step 9:
If we divide 3550 by 420, we get 8 and a remainder of 190.
The next digit of our result is 8. 
Result so far: 86753.8
Subtract 3360 from 3550 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 10:
If we divide 1900 by 420, we get 4 and a remainder of 220.
Put 4 as the next digit of the answer. 
Result so far: 86753.84
If we subtract 1680 from 1900, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 11:
2200 divided by 420 is 5 with a remainder of 100.
The next digit of our result is 5. 
Result so far: 86753.845
Subtract 2100 from 2200 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
When dividing 1000 by 420, we get 2 with a remainder of 160.
The next digit of our result is 2. 
Result so far: 86753.8452
If we subtract 840 from 1000, we get 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 13:
1600 divided by 420 is 3 with a remainder of 340.
Write down 3 as next digit of the result. 
Result so far: 86753.84523
Subtracting 1260 from 1600 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 14:
420 can be fit into 3400 8 times, resulting in a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 86753.845238
The remainder is 40 after subtracting 3360 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 15:
420 can be fit into 400 0 times, resulting in a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 86753.845238
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 16:
4000 divided by 420 is 9 with a remainder of 220.
Use 9 as the next digit of our solution. 
Result so far: 86753.84523809
If we subtract 3780 from 4000, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

In conclusion, the division gives 86753.84523809 with a balance of 2.2e-07.
