We're dividing 85002876 by 643 
Let's see how many times 643 fits into 85002876.

Step 1:
643 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
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 643

Moving on to step 2:
The number 643 fits into 85 0 times, leaving a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Append the next digit (0) from the dividend to 85 and continue with: 850 / 643

Let's proceed to step 3:
643 goes into 850 1 times with a remainder of 207.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 643 from 850, we get 207.
Fetch the next digit (0) from the dividend, attach it to 207 and continue: 2070 / 643

Moving on to step 4:
643 goes into 2070 3 times with a remainder of 141.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 1929 from 2070 and we're left with 141.
Grab the next digit (2) from the dividend, add it to 141, then carry on: 1412 / 643

On to step 5:
If we divide 1412 by 643, we get 2 and a remainder of 126.
The next digit of our result is 2. 
Result so far: 132.0
The remainder is 126 after subtracting 1286 from 1412.
Fetch the next digit (8) from the dividend, attach it to 126 and continue: 1268 / 643

Moving on to step 6:
643 can be fit into 1268 1 times, resulting in a remainder of 625.
The number 1 becomes the next digit in our result. 
Result so far: 1321.0
Subtracting 643 from 1268 leaves us with 625.
Include the next digit (7) from the dividend after 625, then repeat: 6257 / 643

Step 7:
643 can be fit into 6257 9 times, resulting in a remainder of 470.
Record the quotient 9 as the next digit in the result. 
Result so far: 13219.0
If we subtract 5787 from 6257, we get 470.
Take the next digit (6) from the dividend and append it to 470, then repeat: 4706 / 643

Advancing to step 8:
4706 divided by 643 is 7 with a remainder of 205.
The next digit of our result is 7. 
Result so far: 132197.0
If we subtract 4501 from 4706, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 9:
643 can be fit into 2050 3 times, resulting in a remainder of 121.
Write down 3 as next digit of the result. 
Result so far: 132197.3
If we subtract 1929 from 2050, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 10:
643 can be fit into 1210 1 times, resulting in a remainder of 567.
The next digit of our result is 1. 
Result so far: 132197.31
Subtracting 643 from 1210 leaves us with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

On to step 11:
643 can be fit into 5670 8 times, resulting in a remainder of 526.
The next digit of our result is 8. 
Result so far: 132197.318
If we subtract 5144 from 5670, we get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

On to step 12:
643 can be fit into 5260 8 times, resulting in a remainder of 116.
The next digit of our result is 8. 
Result so far: 132197.3188
If we take 5144 away from 5260, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The final result is 132197.3188 with a remainder of 0.00116.
