9261043 divided by 399 
Our goal is to divide 9261043 by 399.

Let's proceed to step 1:
9 divided by 399 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 399

Moving on to step 2:
The number 399 fits into 92 0 times, leaving a remainder of 92.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 92 and we're left with 92.
Append the next digit (6) from the dividend to 92 and continue with: 926 / 399

On to step 3:
926 divided by 399 is 2 with a remainder of 128.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 798 from 926 and we're left with 128.
Grab the next digit (1) from the dividend, add it to 128, then carry on: 1281 / 399

Let's proceed to step 4:
399 goes into 1281 3 times with a remainder of 84.
The next digit of our result is 3. 
Result so far: 23.0
Deduct 1197 from 1281 and we're left with 84.
Take the next digit (0) from the dividend and append it to 84, then repeat: 840 / 399

Step 5:
399 goes into 840 2 times with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 232.0
Deduct 798 from 840 and we're left with 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 399

Moving on to step 6:
424 divided by 399 is 1 with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 2321.0
Deduct 399 from 424 and we're left with 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 399

Going ahead to step 7:
The number 399 fits into 253 0 times, leaving a remainder of 253.
Use 0 as the next digit of our solution. 
Result so far: 23210.0
Subtract 0 from 253 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Let's proceed to step 8:
When dividing 2530 by 399, we get 6 with a remainder of 136.
Put 6 as the next digit of the answer. 
Result so far: 23210.6
Deduct 2394 from 2530 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 9:
When dividing 1360 by 399, we get 3 with a remainder of 163.
Put 3 as the next digit of the answer. 
Result so far: 23210.63
Subtract 1197 from 1360 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Let's proceed to step 10:
The number 399 fits into 1630 4 times, leaving a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 23210.634
Subtract 1596 from 1630 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
The number 399 fits into 340 0 times, leaving a remainder of 340.
The next digit of our result is 0. 
Result so far: 23210.634
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 12:
399 goes into 3400 8 times with a remainder of 208.
Use 8 as the next digit of our solution. 
Result so far: 23210.63408
If we take 3192 away from 3400, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 13:
399 can be fit into 2080 5 times, resulting in a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 23210.634085
If we take 1995 away from 2080, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 14:
850 divided by 399 is 2 with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 23210.6340852
If we subtract 798 from 850, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 15:
If we divide 520 by 399, we get 1 and a remainder of 121.
Use 1 as the next digit of our solution. 
Result so far: 23210.63408521
The remainder is 121 after subtracting 399 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

The quotient of the division is 23210.63408521, and the remainder is 1.21e-07.
