Let's divide 84138435 by 720
The aim is to understand the frequency of 720 in 84138435.

Moving on to step 1:
720 can be fit into 8 0 times, resulting in 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.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 720

Advancing to step 2:
When dividing 84 by 720, we get 0 with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Fetch the next digit (1) from the dividend, attach it to 84 and continue: 841 / 720

Let's proceed to step 3:
720 can be fit into 841 1 times, resulting in a remainder of 121.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 720 from 841 to get 121.
Fetch the next digit (3) from the dividend, attach it to 121 and continue: 1213 / 720

Moving on to step 4:
If we divide 1213 by 720, we get 1 and a remainder of 493.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 720 from 1213 and we're left with 493.
Fetch the next digit (8) from the dividend, attach it to 493 and continue: 4938 / 720

Step 5:
720 goes into 4938 6 times with a remainder of 618.
Put 6 as the next digit of the answer. 
Result so far: 116.0
If we subtract 4320 from 4938, we get 618.
Append the next digit (4) from the dividend to 618 and continue with: 6184 / 720

On to step 6:
720 can be fit into 6184 8 times, resulting in a remainder of 424.
Write down 8 as next digit of the result. 
Result so far: 1168.0
The remainder is 424 after subtracting 5760 from 6184.
Append the next digit (3) from the dividend to 424 and continue with: 4243 / 720

Advancing to step 7:
If we divide 4243 by 720, we get 5 and a remainder of 643.
Write down 5 as next digit of the result. 
Result so far: 11685.0
Subtracting 3600 from 4243 leaves us with 643.
Bring next digit (5) of the dividend behind the 643 and repeat the process: 6435 / 720

On to step 8:
6435 divided by 720 is 8 with a remainder of 675.
Use 8 as the next digit of our solution. 
Result so far: 116858.0
If we take 5760 away from 6435, we end up with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Let's proceed to step 9:
When dividing 6750 by 720, we get 9 with a remainder of 270.
Record the quotient 9 as the next digit in the result. 
Result so far: 116858.9
Subtracting 6480 from 6750 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 10:
If we divide 2700 by 720, we get 3 and a remainder of 540.
Record the quotient 3 as the next digit in the result. 
Result so far: 116858.93
The remainder is 540 after subtracting 2160 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 11:
5400 divided by 720 is 7 with a remainder of 360.
Record the quotient 7 as the next digit in the result. 
Result so far: 116858.937
The remainder is 360 after subtracting 5040 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 12:
720 can be fit into 3600 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 116858.9375
Deduct 3600 from 3600 and we're left 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.

Advancing to step 13:
When dividing 0 by 720, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 116858.9375
If we take 0 away from 0, we end up 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.

Moving on to step 14:
If we divide 0 by 720, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 116858.9375
If we take 0 away from 0, we end up 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.

The final outcome is 116858.9375, with a leftover of 0.0.
