Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 999

Step 2:
999 goes into 90 0 times with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Fetch the next digit (3) from the dividend, attach it to 90 and continue: 903 / 999

Let's proceed to step 3:
999 goes into 903 0 times with a remainder of 903.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 903 leaves us with 903.
Grab the next digit (1) from the dividend, add it to 903, then carry on: 9031 / 999

Advancing to step 4:
If we divide 9031 by 999, we get 9 and a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 40 after subtracting 8991 from 9031.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 999

Moving on to step 5:
When dividing 403 by 999, we get 0 with a remainder of 403.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Subtracting 0 from 403 leaves us with 403.
Take the next digit (4) from the dividend and append it to 403, then repeat: 4034 / 999

Moving on to step 6:
999 goes into 4034 4 times with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 904.0
Deduct 3996 from 4034 and we're left with 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 999

Moving on to step 7:
The number 999 fits into 381 0 times, leaving a remainder of 381.
Use 0 as the next digit of our solution. 
Result so far: 9040.0
Deduct 0 from 381 and we're left with 381.
Append the next digit (0) from the dividend to 381 and continue with: 3810 / 999

On to step 8:
If we divide 3810 by 999, we get 3 and a remainder of 813.
The number 3 becomes the next digit in our result. 
Result so far: 90403.0
Deduct 2997 from 3810 and we're left with 813.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8130, and continue the process.

Advancing to step 9:
When dividing 8130 by 999, we get 8 with a remainder of 138.
Write down 8 as next digit of the result. 
Result so far: 90403.8
Deduct 7992 from 8130 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 10:
999 can be fit into 1380 1 times, resulting in a remainder of 381.
Use 1 as the next digit of our solution. 
Result so far: 90403.81
Deduct 999 from 1380 and we're left with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 11:
999 can be fit into 3810 3 times, resulting in a remainder of 813.
Put 3 as the next digit of the answer. 
Result so far: 90403.813
Subtract 2997 from 3810 to get 813.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8130, and continue the process.

Let's proceed to step 12:
8130 divided by 999 is 8 with a remainder of 138.
Put 8 as the next digit of the answer. 
Result so far: 90403.8138
Subtracting 7992 from 8130 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 13:
The number 999 fits into 1380 1 times, leaving a remainder of 381.
The next digit of our result is 1. 
Result so far: 90403.81381
Subtract 999 from 1380 to get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 14:
The number 999 fits into 3810 3 times, leaving a remainder of 813.
Use 3 as the next digit of our solution. 
Result so far: 90403.813813
Subtract 2997 from 3810 to get 813.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8130, and continue the process.

Step 15:
The number 999 fits into 8130 8 times, leaving a remainder of 138.
Use 8 as the next digit of our solution. 
Result so far: 90403.8138138
The remainder is 138 after subtracting 7992 from 8130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 16:
999 can be fit into 1380 1 times, resulting in a remainder of 381.
Use 1 as the next digit of our solution. 
Result so far: 90403.81381381
Subtracting 999 from 1380 leaves us with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

The final outcome is 90403.81381381, with a leftover of 3.81e-07.
