The number 643 fits into 4020 6 times, leaving a remainder of 162.
The number 6 becomes the next digit in our result. 
Result so far: 98894.6
Subtract 3858 from 4020 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 10:
When dividing 1620 by 643, we get 2 with a remainder of 334.
Write down 2 as next digit of the result. 
Result so far: 98894.62
Subtracting 1286 from 1620 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 11:
643 can be fit into 3340 5 times, resulting in a remainder of 125.
The next digit of our result is 5. 
Result so far: 98894.625
The remainder is 125 after subtracting 3215 from 3340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 12:
The number 643 fits into 1250 1 times, leaving a remainder of 607.
Put 1 as the next digit of the answer. 
Result so far: 98894.6251
Subtract 643 from 1250 to get 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Moving on to step 13:
6070 divided by 643 is 9 with a remainder of 283.
Write down 9 as next digit of the result. 
Result so far: 98894.62519
Subtracting 5787 from 6070 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Going ahead to step 14:
The number 643 fits into 2830 4 times, leaving a remainder of 258.
The next digit of our result is 4. 
Result so far: 98894.625194
Subtract 2572 from 2830 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 15:
If we divide 2580 by 643, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 98894.6251944
If we subtract 2572 from 2580, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 98894.6251944 with a remaining 8e-08.
