80359507 divided by 986 
The aim is to understand the frequency of 986 in 80359507.

On to step 1:
986 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 986

Step 2:
When dividing 80 by 986, we get 0 with 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.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 986

Step 3:
The number 986 fits into 803 0 times, leaving a remainder of 803.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 803, we get 803.
Fetch the next digit (5) from the dividend, attach it to 803 and continue: 8035 / 986

Step 4:
The number 986 fits into 8035 8 times, leaving a remainder of 147.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 7888 from 8035 leaves us with 147.
Grab the next digit (9) from the dividend, add it to 147, then carry on: 1479 / 986

Let's proceed to step 5:
1479 divided by 986 is 1 with a remainder of 493.
The next digit of our result is 1. 
Result so far: 81.0
Subtract 986 from 1479 to get 493.
Append the next digit (5) from the dividend to 493 and continue with: 4935 / 986

Step 6:
When dividing 4935 by 986, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 815.0
The remainder is 5 after subtracting 4930 from 4935.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 986

Let's proceed to step 7:
When dividing 50 by 986, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 8150.0
Deduct 0 from 50 and we're left with 50.
Take the next digit (7) from the dividend and append it to 50, then repeat: 507 / 986

Step 8:
When dividing 507 by 986, we get 0 with a remainder of 507.
Put 0 as the next digit of the answer. 
Result so far: 81500.0
If we take 0 away from 507, we end up with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Step 9:
5070 divided by 986 is 5 with a remainder of 140.
The next digit of our result is 5. 
Result so far: 81500.5
If we subtract 4930 from 5070, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
The number 986 fits into 1400 1 times, leaving a remainder of 414.
Put 1 as the next digit of the answer. 
Result so far: 81500.51
If we subtract 986 from 1400, we get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Going ahead to step 11:
986 goes into 4140 4 times with a remainder of 196.
The next digit of our result is 4. 
Result so far: 81500.514
Subtract 3944 from 4140 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 12:
986 goes into 1960 1 times with a remainder of 974.
Put 1 as the next digit of the answer. 
Result so far: 81500.5141
The remainder is 974 after subtracting 986 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9740, and continue the process.

Step 13:
986 can be fit into 9740 9 times, resulting in a remainder of 866.
Write down 9 as next digit of the result. 
Result so far: 81500.51419
If we take 8874 away from 9740, we end up with 866.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8660, and continue the process.

Going ahead to step 14:
986 can be fit into 8660 8 times, resulting in a remainder of 772.
The number 8 becomes the next digit in our result. 
Result so far: 81500.514198
Deduct 7888 from 8660 and we're left with 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Step 15:
986 goes into 7720 7 times with a remainder of 818.
Put 7 as the next digit of the answer. 
Result so far: 81500.5141987
Subtract 6902 from 7720 to get 818.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8180, and continue the process.

Moving on to step 16:
8180 divided by 986 is 8 with a remainder of 292.
The next digit of our result is 8. 
Result so far: 81500.51419878
Deduct 7888 from 8180 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

After the division, we end up with 81500.51419878 and a remainder of 2.92e-07.
