We look at the division of 9052095 by 399 
Let's see how many times 399 fits into 9052095.

On to step 1:
The number 399 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 399

On to step 2:
The number 399 fits into 90 0 times, leaving a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Fetch the next digit (5) from the dividend, attach it to 90 and continue: 905 / 399

Advancing to step 3:
If we divide 905 by 399, we get 2 and a remainder of 107.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 798 from 905, we get 107.
Take the next digit (2) from the dividend and append it to 107, then repeat: 1072 / 399

On to step 4:
If we divide 1072 by 399, we get 2 and a remainder of 274.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we subtract 798 from 1072, we get 274.
Grab the next digit (0) from the dividend, add it to 274, then carry on: 2740 / 399

On to step 5:
2740 divided by 399 is 6 with a remainder of 346.
The number 6 becomes the next digit in our result. 
Result so far: 226.0
The remainder is 346 after subtracting 2394 from 2740.
Include the next digit (9) from the dividend after 346, then repeat: 3469 / 399

Step 6:
If we divide 3469 by 399, we get 8 and a remainder of 277.
Put 8 as the next digit of the answer. 
Result so far: 2268.0
Subtract 3192 from 3469 to get 277.
Fetch the next digit (5) from the dividend, attach it to 277 and continue: 2775 / 399

Going ahead to step 7:
399 can be fit into 2775 6 times, resulting in a remainder of 381.
The number 6 becomes the next digit in our result. 
Result so far: 22686.0
Subtract 2394 from 2775 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.

Moving on to step 8:
If we divide 3810 by 399, we get 9 and a remainder of 219.
Use 9 as the next digit of our solution. 
Result so far: 22686.9
If we subtract 3591 from 3810, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Moving on to step 9:
399 goes into 2190 5 times with a remainder of 195.
Write down 5 as next digit of the result. 
Result so far: 22686.95
The remainder is 195 after subtracting 1995 from 2190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 10:
1950 divided by 399 is 4 with a remainder of 354.
Put 4 as the next digit of the answer. 
Result so far: 22686.954
If we subtract 1596 from 1950, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 11:
399 goes into 3540 8 times with a remainder of 348.
Write down 8 as next digit of the result. 
Result so far: 22686.9548
Deduct 3192 from 3540 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 12:
399 goes into 3480 8 times with a remainder of 288.
Record the quotient 8 as the next digit in the result. 
Result so far: 22686.95488
Subtracting 3192 from 3480 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Our division results in 22686.95488 with a remaining 0.000288.
