83987976 divided by 847 
The aim is to understand the frequency of 847 in 83987976.

Moving on to step 1:
8 divided by 847 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 847

Step 2:
847 can be fit into 83 0 times, resulting in a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Grab the next digit (9) from the dividend, add it to 83, then carry on: 839 / 847

Step 3:
847 can be fit into 839 0 times, resulting in a remainder of 839.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 839, we end up with 839.
Fetch the next digit (8) from the dividend, attach it to 839 and continue: 8398 / 847

Going ahead to step 4:
When dividing 8398 by 847, we get 9 with a remainder of 775.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 7623 away from 8398, we end up with 775.
Bring next digit (7) of the dividend behind the 775 and repeat the process: 7757 / 847

Advancing to step 5:
847 goes into 7757 9 times with a remainder of 134.
Put 9 as the next digit of the answer. 
Result so far: 99.0
Subtracting 7623 from 7757 leaves us with 134.
Take the next digit (9) from the dividend and append it to 134, then repeat: 1349 / 847

Let's proceed to step 6:
When dividing 1349 by 847, we get 1 with a remainder of 502.
The next digit of our result is 1. 
Result so far: 991.0
The remainder is 502 after subtracting 847 from 1349.
Append the next digit (7) from the dividend to 502 and continue with: 5027 / 847

Moving on to step 7:
When dividing 5027 by 847, we get 5 with a remainder of 792.
The next digit of our result is 5. 
Result so far: 9915.0
Subtract 4235 from 5027 to get 792.
Include the next digit (6) from the dividend after 792, then repeat: 7926 / 847

Advancing to step 8:
7926 divided by 847 is 9 with a remainder of 303.
Write down 9 as next digit of the result. 
Result so far: 99159.0
Deduct 7623 from 7926 and we're left with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Going ahead to step 9:
When dividing 3030 by 847, we get 3 with a remainder of 489.
Use 3 as the next digit of our solution. 
Result so far: 99159.3
Subtracting 2541 from 3030 leaves us with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Step 10:
847 goes into 4890 5 times with a remainder of 655.
Record the quotient 5 as the next digit in the result. 
Result so far: 99159.35
If we take 4235 away from 4890, we end up with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Let's proceed to step 11:
847 can be fit into 6550 7 times, resulting in a remainder of 621.
Write down 7 as next digit of the result. 
Result so far: 99159.357
If we subtract 5929 from 6550, we get 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Step 12:
847 goes into 6210 7 times with a remainder of 281.
Write down 7 as next digit of the result. 
Result so far: 99159.3577
The remainder is 281 after subtracting 5929 from 6210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

After the division, we end up with 99159.3577 and a remainder of 0.00281.
