We look at the division of 86308557 by 983 
The aim is to understand the frequency of 983 in 86308557.

Moving on to step 1:
983 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 983

Going ahead to step 2:
The number 983 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Grab the next digit (3) from the dividend, add it to 86, then carry on: 863 / 983

On to step 3:
The number 983 fits into 863 0 times, leaving a remainder of 863.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 863 leaves us with 863.
Grab the next digit (0) from the dividend, add it to 863, then carry on: 8630 / 983

Going ahead to step 4:
When dividing 8630 by 983, we get 8 with a remainder of 766.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 766 after subtracting 7864 from 8630.
Append the next digit (8) from the dividend to 766 and continue with: 7668 / 983

Moving on to step 5:
983 can be fit into 7668 7 times, resulting in a remainder of 787.
Write down 7 as next digit of the result. 
Result so far: 87.0
Deduct 6881 from 7668 and we're left with 787.
Grab the next digit (5) from the dividend, add it to 787, then carry on: 7875 / 983

Moving on to step 6:
7875 divided by 983 is 8 with a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 878.0
Subtract 7864 from 7875 to get 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 983

Let's proceed to step 7:
If we divide 115 by 983, we get 0 and a remainder of 115.
Put 0 as the next digit of the answer. 
Result so far: 8780.0
The remainder is 115 after subtracting 0 from 115.
Fetch the next digit (7) from the dividend, attach it to 115 and continue: 1157 / 983

Step 8:
If we divide 1157 by 983, we get 1 and a remainder of 174.
The next digit of our result is 1. 
Result so far: 87801.0
If we subtract 983 from 1157, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 9:
983 goes into 1740 1 times with a remainder of 757.
Record the quotient 1 as the next digit in the result. 
Result so far: 87801.1
Subtracting 983 from 1740 leaves us with 757.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7570, and continue the process.

Moving on to step 10:
983 can be fit into 7570 7 times, resulting in a remainder of 689.
Record the quotient 7 as the next digit in the result. 
Result so far: 87801.17
Deduct 6881 from 7570 and we're left with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Going ahead to step 11:
983 can be fit into 6890 7 times, resulting in a remainder of 9.
The next digit of our result is 7. 
Result so far: 87801.177
If we take 6881 away from 6890, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 87801.177, and the remainder is 0.0009.
