84558980 ÷ 652 
The aim is to understand the frequency of 652 in 84558980.

Advancing to step 1:
When dividing 8 by 652, we get 0 with 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.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 652

Going ahead to step 2:
84 divided by 652 is 0 with a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Bring next digit (5) of the dividend behind the 84 and repeat the process: 845 / 652

Going ahead to step 3:
If we divide 845 by 652, we get 1 and a remainder of 193.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 193 after subtracting 652 from 845.
Fetch the next digit (5) from the dividend, attach it to 193 and continue: 1935 / 652

Let's proceed to step 4:
If we divide 1935 by 652, we get 2 and a remainder of 631.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1304 from 1935 to get 631.
Fetch the next digit (8) from the dividend, attach it to 631 and continue: 6318 / 652

On to step 5:
652 can be fit into 6318 9 times, resulting in a remainder of 450.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
Subtract 5868 from 6318 to get 450.
Take the next digit (9) from the dividend and append it to 450, then repeat: 4509 / 652

Going ahead to step 6:
652 can be fit into 4509 6 times, resulting in a remainder of 597.
Use 6 as the next digit of our solution. 
Result so far: 1296.0
If we take 3912 away from 4509, we end up with 597.
Grab the next digit (8) from the dividend, add it to 597, then carry on: 5978 / 652

Moving on to step 7:
If we divide 5978 by 652, we get 9 and a remainder of 110.
Put 9 as the next digit of the answer. 
Result so far: 12969.0
Subtracting 5868 from 5978 leaves us with 110.
Bring next digit (0) of the dividend behind the 110 and repeat the process: 1100 / 652

Advancing to step 8:
When dividing 1100 by 652, we get 1 with a remainder of 448.
Put 1 as the next digit of the answer. 
Result so far: 129691.0
If we subtract 652 from 1100, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 9:
652 can be fit into 4480 6 times, resulting in a remainder of 568.
The number 6 becomes the next digit in our result. 
Result so far: 129691.6
If we take 3912 away from 4480, we end up with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Advancing to step 10:
652 can be fit into 5680 8 times, resulting in a remainder of 464.
The number 8 becomes the next digit in our result. 
Result so far: 129691.68
Deduct 5216 from 5680 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 11:
652 goes into 4640 7 times with a remainder of 76.
Write down 7 as next digit of the result. 
Result so far: 129691.687
If we take 4564 away from 4640, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 12:
652 goes into 760 1 times with a remainder of 108.
The next digit of our result is 1. 
Result so far: 129691.6871
If we subtract 652 from 760, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 13:
1080 divided by 652 is 1 with a remainder of 428.
Put 1 as the next digit of the answer. 
Result so far: 129691.68711
If we take 652 away from 1080, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

The final outcome is 129691.68711, with a leftover of 0.000428.
