Let's divide 87859508 by 986
The aim is to understand the frequency of 986 in 87859508.

On to step 1:
If we divide 8 by 986, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 986

On to step 2:
986 can be fit into 87 0 times, resulting in a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Take the next digit (8) from the dividend and append it to 87, then repeat: 878 / 986

Going ahead to step 3:
When dividing 878 by 986, we get 0 with a remainder of 878.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 878 after subtracting 0 from 878.
Include the next digit (5) from the dividend after 878, then repeat: 8785 / 986

Let's proceed to step 4:
When dividing 8785 by 986, we get 8 with a remainder of 897.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 7888 from 8785 and we're left with 897.
Take the next digit (9) from the dividend and append it to 897, then repeat: 8979 / 986

Let's proceed to step 5:
986 goes into 8979 9 times with a remainder of 105.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
If we take 8874 away from 8979, we end up with 105.
Append the next digit (5) from the dividend to 105 and continue with: 1055 / 986

On to step 6:
1055 divided by 986 is 1 with a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 891.0
Subtract 986 from 1055 to get 69.
Take the next digit (0) from the dividend and append it to 69, then repeat: 690 / 986

Let's proceed to step 7:
If we divide 690 by 986, we get 0 and a remainder of 690.
The number 0 becomes the next digit in our result. 
Result so far: 8910.0
If we subtract 0 from 690, we get 690.
Fetch the next digit (8) from the dividend, attach it to 690 and continue: 6908 / 986

On to step 8:
When dividing 6908 by 986, we get 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 89107.0
Subtract 6902 from 6908 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
986 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 89107.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
The number 986 fits into 600 0 times, leaving a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 89107.0
Subtract 0 from 600 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The quotient of the division is 89107.0, and the remainder is 0.6.
