We look at the division of 3213872 by 904 
We want to divide 3213872 by 904.

Moving on to step 1:
904 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 904

On to step 2:
When dividing 32 by 904, we get 0 with a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 32 after subtracting 0 from 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 904

Step 3:
If we divide 321 by 904, we get 0 and a remainder of 321.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 321 leaves us with 321.
Bring next digit (3) of the dividend behind the 321 and repeat the process: 3213 / 904

Advancing to step 4:
904 can be fit into 3213 3 times, resulting in a remainder of 501.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 501 after subtracting 2712 from 3213.
Bring next digit (8) of the dividend behind the 501 and repeat the process: 5018 / 904

On to step 5:
904 goes into 5018 5 times with a remainder of 498.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtract 4520 from 5018 to get 498.
Append the next digit (7) from the dividend to 498 and continue with: 4987 / 904

Let's proceed to step 6:
When dividing 4987 by 904, we get 5 with a remainder of 467.
Record the quotient 5 as the next digit in the result. 
Result so far: 355.0
Deduct 4520 from 4987 and we're left with 467.
Grab the next digit (2) from the dividend, add it to 467, then carry on: 4672 / 904

Let's proceed to step 7:
When dividing 4672 by 904, we get 5 with a remainder of 152.
Use 5 as the next digit of our solution. 
Result so far: 3555.0
The remainder is 152 after subtracting 4520 from 4672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 8:
When dividing 1520 by 904, we get 1 with a remainder of 616.
The next digit of our result is 1. 
Result so far: 3555.1
Subtract 904 from 1520 to get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

On to step 9:
The number 904 fits into 6160 6 times, leaving a remainder of 736.
Use 6 as the next digit of our solution. 
Result so far: 3555.16
The remainder is 736 after subtracting 5424 from 6160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Moving on to step 10:
If we divide 7360 by 904, we get 8 and a remainder of 128.
Use 8 as the next digit of our solution. 
Result so far: 3555.168
If we subtract 7232 from 7360, we 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.

On to step 11:
1280 divided by 904 is 1 with a remainder of 376.
Record the quotient 1 as the next digit in the result. 
Result so far: 3555.1681
The remainder is 376 after subtracting 904 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 12:
904 can be fit into 3760 4 times, resulting in a remainder of 144.
Use 4 as the next digit of our solution. 
Result so far: 3555.16814
Subtracting 3616 from 3760 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 13:
1440 divided by 904 is 1 with a remainder of 536.
Write down 1 as next digit of the result. 
Result so far: 3555.168141
Deduct 904 from 1440 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

On to step 14:
If we divide 5360 by 904, we get 5 and a remainder of 840.
Use 5 as the next digit of our solution. 
Result so far: 3555.1681415
The remainder is 840 after subtracting 4520 from 5360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Moving on to step 15:
8400 divided by 904 is 9 with a remainder of 264.
Use 9 as the next digit of our solution. 
Result so far: 3555.16814159
Subtracting 8136 from 8400 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

After the division, we end up with 3555.16814159 and a remainder of 2.64e-07.
