We look at the division of 89980520 by 628 
The aim is to understand the frequency of 628 in 89980520.

Moving on to step 1:
If we divide 8 by 628, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 628

Step 2:
The number 628 fits into 89 0 times, leaving a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Grab the next digit (9) from the dividend, add it to 89, then carry on: 899 / 628

On to step 3:
The number 628 fits into 899 1 times, leaving a remainder of 271.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 628 from 899 leaves us with 271.
Append the next digit (8) from the dividend to 271 and continue with: 2718 / 628

Let's proceed to step 4:
628 can be fit into 2718 4 times, resulting in a remainder of 206.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 2512 from 2718 and we're left with 206.
Grab the next digit (0) from the dividend, add it to 206, then carry on: 2060 / 628

Going ahead to step 5:
628 goes into 2060 3 times with a remainder of 176.
Write down 3 as next digit of the result. 
Result so far: 143.0
Subtracting 1884 from 2060 leaves us with 176.
Include the next digit (5) from the dividend after 176, then repeat: 1765 / 628

Going ahead to step 6:
When dividing 1765 by 628, we get 2 with a remainder of 509.
Put 2 as the next digit of the answer. 
Result so far: 1432.0
Deduct 1256 from 1765 and we're left with 509.
Grab the next digit (2) from the dividend, add it to 509, then carry on: 5092 / 628

On to step 7:
If we divide 5092 by 628, we get 8 and a remainder of 68.
The next digit of our result is 8. 
Result so far: 14328.0
Subtract 5024 from 5092 to get 68.
Take the next digit (0) from the dividend and append it to 68, then repeat: 680 / 628

On to step 8:
If we divide 680 by 628, we get 1 and a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 143281.0
Subtract 628 from 680 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
The number 628 fits into 520 0 times, leaving a remainder of 520.
The next digit of our result is 0. 
Result so far: 143281.0
Subtract 0 from 520 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 10:
5200 divided by 628 is 8 with a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 143281.08
Deduct 5024 from 5200 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 11:
When dividing 1760 by 628, we get 2 with a remainder of 504.
Write down 2 as next digit of the result. 
Result so far: 143281.082
If we subtract 1256 from 1760, we get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 12:
If we divide 5040 by 628, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 143281.0828
Deduct 5024 from 5040 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
160 divided by 628 is 0 with a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 143281.0828
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
The number 628 fits into 1600 2 times, leaving a remainder of 344.
Put 2 as the next digit of the answer. 
Result so far: 143281.082802
The remainder is 344 after subtracting 1256 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 15:
628 can be fit into 3440 5 times, resulting in a remainder of 300.
Use 5 as the next digit of our solution. 
Result so far: 143281.0828025
Deduct 3140 from 3440 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 16:
If we divide 3000 by 628, we get 4 and a remainder of 488.
Write down 4 as next digit of the result. 
Result so far: 143281.08280254
Deduct 2512 from 3000 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

In conclusion, the division gives 143281.08280254 with a balance of 4.88e-07.
