3397475 divided by 864 
Let's see how many times 864 fits into 3397475.

Moving on to step 1:
If we divide 3 by 864, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 864

Let's proceed to step 2:
If we divide 33 by 864, we get 0 and a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 864

Let's proceed to step 3:
864 goes into 339 0 times with a remainder of 339.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 339 leaves us with 339.
Bring next digit (7) of the dividend behind the 339 and repeat the process: 3397 / 864

Advancing to step 4:
When dividing 3397 by 864, we get 3 with a remainder of 805.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 805 after subtracting 2592 from 3397.
Grab the next digit (4) from the dividend, add it to 805, then carry on: 8054 / 864

Step 5:
8054 divided by 864 is 9 with a remainder of 278.
Use 9 as the next digit of our solution. 
Result so far: 39.0
The remainder is 278 after subtracting 7776 from 8054.
Take the next digit (7) from the dividend and append it to 278, then repeat: 2787 / 864

Let's proceed to step 6:
864 can be fit into 2787 3 times, resulting in a remainder of 195.
Use 3 as the next digit of our solution. 
Result so far: 393.0
Subtract 2592 from 2787 to get 195.
Grab the next digit (5) from the dividend, add it to 195, then carry on: 1955 / 864

Step 7:
The number 864 fits into 1955 2 times, leaving a remainder of 227.
The number 2 becomes the next digit in our result. 
Result so far: 3932.0
Subtract 1728 from 1955 to get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Going ahead to step 8:
The number 864 fits into 2270 2 times, leaving a remainder of 542.
The next digit of our result is 2. 
Result so far: 3932.2
The remainder is 542 after subtracting 1728 from 2270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Step 9:
The number 864 fits into 5420 6 times, leaving a remainder of 236.
Use 6 as the next digit of our solution. 
Result so far: 3932.26
The remainder is 236 after subtracting 5184 from 5420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 10:
864 goes into 2360 2 times with a remainder of 632.
The number 2 becomes the next digit in our result. 
Result so far: 3932.262
The remainder is 632 after subtracting 1728 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Let's proceed to step 11:
The number 864 fits into 6320 7 times, leaving a remainder of 272.
The next digit of our result is 7. 
Result so far: 3932.2627
Deduct 6048 from 6320 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 12:
If we divide 2720 by 864, we get 3 and a remainder of 128.
Record the quotient 3 as the next digit in the result. 
Result so far: 3932.26273
Subtract 2592 from 2720 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 13:
1280 divided by 864 is 1 with a remainder of 416.
Record the quotient 1 as the next digit in the result. 
Result so far: 3932.262731
Subtract 864 from 1280 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 14:
The number 864 fits into 4160 4 times, leaving a remainder of 704.
The number 4 becomes the next digit in our result. 
Result so far: 3932.2627314
If we subtract 3456 from 4160, we get 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Advancing to step 15:
The number 864 fits into 7040 8 times, leaving a remainder of 128.
Use 8 as the next digit of our solution. 
Result so far: 3932.26273148
The remainder is 128 after subtracting 6912 from 7040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 3932.26273148, with a leftover of 1.28e-07.
