On to step 5:
The number 869 fits into 8364 9 times, leaving a remainder of 543.
Put 9 as the next digit of the answer. 
Result so far: 89.0
If we subtract 7821 from 8364, we get 543.
Include the next digit (1) from the dividend after 543, then repeat: 5431 / 869

On to step 6:
869 can be fit into 5431 6 times, resulting in a remainder of 217.
Put 6 as the next digit of the answer. 
Result so far: 896.0
Subtract 5214 from 5431 to get 217.
Fetch the next digit (9) from the dividend, attach it to 217 and continue: 2179 / 869

Let's proceed to step 7:
869 goes into 2179 2 times with a remainder of 441.
Record the quotient 2 as the next digit in the result. 
Result so far: 8962.0
If we subtract 1738 from 2179, we get 441.
Grab the next digit (7) from the dividend, add it to 441, then carry on: 4417 / 869

Moving on to step 8:
The number 869 fits into 4417 5 times, leaving a remainder of 72.
Put 5 as the next digit of the answer. 
Result so far: 89625.0
If we subtract 4345 from 4417, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 9:
720 divided by 869 is 0 with a remainder of 720.
Use 0 as the next digit of our solution. 
Result so far: 89625.0
The remainder is 720 after subtracting 0 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 10:
869 goes into 7200 8 times with a remainder of 248.
The next digit of our result is 8. 
Result so far: 89625.08
If we subtract 6952 from 7200, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 11:
2480 divided by 869 is 2 with a remainder of 742.
Put 2 as the next digit of the answer. 
Result so far: 89625.082
Subtract 1738 from 2480 to get 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Let's proceed to step 12:
When dividing 7420 by 869, we get 8 with a remainder of 468.
Record the quotient 8 as the next digit in the result. 
Result so far: 89625.0828
If we subtract 6952 from 7420, we get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Advancing to step 13:
869 goes into 4680 5 times with a remainder of 335.
Put 5 as the next digit of the answer. 
Result so far: 89625.08285
If we subtract 4345 from 4680, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Step 14:
869 can be fit into 3350 3 times, resulting in a remainder of 743.
The number 3 becomes the next digit in our result. 
Result so far: 89625.082853
Deduct 2607 from 3350 and we're left with 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Advancing to step 15:
869 goes into 7430 8 times with a remainder of 478.
Write down 8 as next digit of the result. 
Result so far: 89625.0828538
Subtract 6952 from 7430 to get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

On to step 16:
4780 divided by 869 is 5 with a remainder of 435.
Put 5 as the next digit of the answer. 
Result so far: 89625.08285385
Subtracting 4345 from 4780 leaves us with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

After the division, we end up with 89625.08285385 and a remainder of 4.35e-07.
