We divide 80089986 by 655
The aim is to understand the frequency of 655 in 80089986.

On to step 1:
The number 655 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.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 655

Advancing to step 2:
The number 655 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Append the next digit (0) from the dividend to 80 and continue with: 800 / 655

Advancing to step 3:
If we divide 800 by 655, we get 1 and a remainder of 145.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 655 from 800 to get 145.
Include the next digit (8) from the dividend after 145, then repeat: 1458 / 655

Step 4:
When dividing 1458 by 655, we get 2 with a remainder of 148.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 1310 from 1458 and we're left with 148.
Include the next digit (9) from the dividend after 148, then repeat: 1489 / 655

Step 5:
The number 655 fits into 1489 2 times, leaving a remainder of 179.
Put 2 as the next digit of the answer. 
Result so far: 122.0
Subtracting 1310 from 1489 leaves us with 179.
Fetch the next digit (9) from the dividend, attach it to 179 and continue: 1799 / 655

Advancing to step 6:
If we divide 1799 by 655, we get 2 and a remainder of 489.
Use 2 as the next digit of our solution. 
Result so far: 1222.0
The remainder is 489 after subtracting 1310 from 1799.
Fetch the next digit (8) from the dividend, attach it to 489 and continue: 4898 / 655

Step 7:
If we divide 4898 by 655, we get 7 and a remainder of 313.
Use 7 as the next digit of our solution. 
Result so far: 12227.0
If we take 4585 away from 4898, we end up with 313.
Bring next digit (6) of the dividend behind the 313 and repeat the process: 3136 / 655

Moving on to step 8:
If we divide 3136 by 655, we get 4 and a remainder of 516.
Record the quotient 4 as the next digit in the result. 
Result so far: 122274.0
Subtract 2620 from 3136 to get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Going ahead to step 9:
5160 divided by 655 is 7 with a remainder of 575.
Write down 7 as next digit of the result. 
Result so far: 122274.7
If we take 4585 away from 5160, we end up with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Advancing to step 10:
655 can be fit into 5750 8 times, resulting in a remainder of 510.
Write down 8 as next digit of the result. 
Result so far: 122274.78
Subtracting 5240 from 5750 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 11:
The number 655 fits into 5100 7 times, leaving a remainder of 515.
Put 7 as the next digit of the answer. 
Result so far: 122274.787
The remainder is 515 after subtracting 4585 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Advancing to step 12:
5150 divided by 655 is 7 with a remainder of 565.
Put 7 as the next digit of the answer. 
Result so far: 122274.7877
Deduct 4585 from 5150 and we're left with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

The quotient of the division is 122274.7877, and the remainder is 0.00565.
