Let's divide 9008903 by 399
Our goal is to divide 9008903 by 399.

Let's proceed to step 1:
399 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 399

Advancing to step 2:
90 divided by 399 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Grab the next digit (0) from the dividend, add it to 90, then carry on: 900 / 399

Going ahead to step 3:
The number 399 fits into 900 2 times, leaving a remainder of 102.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 798 from 900 and we're left with 102.
Fetch the next digit (8) from the dividend, attach it to 102 and continue: 1028 / 399

Step 4:
When dividing 1028 by 399, we get 2 with a remainder of 230.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Deduct 798 from 1028 and we're left with 230.
Grab the next digit (9) from the dividend, add it to 230, then carry on: 2309 / 399

Let's proceed to step 5:
2309 divided by 399 is 5 with a remainder of 314.
Record the quotient 5 as the next digit in the result. 
Result so far: 225.0
If we take 1995 away from 2309, we end up with 314.
Fetch the next digit (0) from the dividend, attach it to 314 and continue: 3140 / 399

Step 6:
If we divide 3140 by 399, we get 7 and a remainder of 347.
Put 7 as the next digit of the answer. 
Result so far: 2257.0
Deduct 2793 from 3140 and we're left with 347.
Fetch the next digit (3) from the dividend, attach it to 347 and continue: 3473 / 399

Step 7:
When dividing 3473 by 399, we get 8 with a remainder of 281.
The next digit of our result is 8. 
Result so far: 22578.0
If we take 3192 away from 3473, we end up with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Going ahead to step 8:
When dividing 2810 by 399, we get 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 22578.7
If we take 2793 away from 2810, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
The number 399 fits into 170 0 times, leaving a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 22578.7
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 10:
The number 399 fits into 1700 4 times, leaving a remainder of 104.
Use 4 as the next digit of our solution. 
Result so far: 22578.704
If we take 1596 away from 1700, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 11:
When dividing 1040 by 399, we get 2 with a remainder of 242.
The next digit of our result is 2. 
Result so far: 22578.7042
Subtract 798 from 1040 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Let's proceed to step 12:
The number 399 fits into 2420 6 times, leaving a remainder of 26.
The next digit of our result is 6. 
Result so far: 22578.70426
The remainder is 26 after subtracting 2394 from 2420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
When dividing 260 by 399, we get 0 with a remainder of 260.
Record the quotient 0 as the next digit in the result. 
Result so far: 22578.70426
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 14:
2600 divided by 399 is 6 with a remainder of 206.
Write down 6 as next digit of the result. 
Result so far: 22578.7042606
If we take 2394 away from 2600, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 15:
The number 399 fits into 2060 5 times, leaving a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 22578.70426065
Subtract 1995 from 2060 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 22578.70426065 with a remaining 6.5e-08.
