3215188 divided by 807 
Let's see how many times 807 fits into 3215188.

Step 1:
807 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 807

Let's proceed to step 2:
When dividing 32 by 807, we get 0 with a remainder of 32.
The number 0 becomes the next digit in our result. 
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 / 807

Let's proceed to step 3:
807 can be fit into 321 0 times, resulting in a remainder of 321.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 321, we get 321.
Bring next digit (5) of the dividend behind the 321 and repeat the process: 3215 / 807

Advancing to step 4:
807 can be fit into 3215 3 times, resulting in a remainder of 794.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 2421 from 3215 leaves us with 794.
Include the next digit (1) from the dividend after 794, then repeat: 7941 / 807

Moving on to step 5:
807 goes into 7941 9 times with a remainder of 678.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we subtract 7263 from 7941, we get 678.
Take the next digit (8) from the dividend and append it to 678, then repeat: 6788 / 807

Step 6:
807 can be fit into 6788 8 times, resulting in a remainder of 332.
Write down 8 as next digit of the result. 
Result so far: 398.0
Subtract 6456 from 6788 to get 332.
Take the next digit (8) from the dividend and append it to 332, then repeat: 3328 / 807

Advancing to step 7:
The number 807 fits into 3328 4 times, leaving a remainder of 100.
The next digit of our result is 4. 
Result so far: 3984.0
If we take 3228 away from 3328, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 8:
When dividing 1000 by 807, we get 1 with a remainder of 193.
The number 1 becomes the next digit in our result. 
Result so far: 3984.1
Subtracting 807 from 1000 leaves us with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Going ahead to step 9:
807 goes into 1930 2 times with a remainder of 316.
Record the quotient 2 as the next digit in the result. 
Result so far: 3984.12
Subtract 1614 from 1930 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 10:
807 can be fit into 3160 3 times, resulting in a remainder of 739.
The next digit of our result is 3. 
Result so far: 3984.123
Deduct 2421 from 3160 and we're left with 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Step 11:
If we divide 7390 by 807, we get 9 and a remainder of 127.
The number 9 becomes the next digit in our result. 
Result so far: 3984.1239
Deduct 7263 from 7390 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 12:
If we divide 1270 by 807, we get 1 and a remainder of 463.
Record the quotient 1 as the next digit in the result. 
Result so far: 3984.12391
Deduct 807 from 1270 and we're left with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

On to step 13:
4630 divided by 807 is 5 with a remainder of 595.
The number 5 becomes the next digit in our result. 
Result so far: 3984.123915
Subtract 4035 from 4630 to get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Let's proceed to step 14:
807 can be fit into 5950 7 times, resulting in a remainder of 301.
Put 7 as the next digit of the answer. 
Result so far: 3984.1239157
Subtracting 5649 from 5950 leaves us with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Let's proceed to step 15:
807 can be fit into 3010 3 times, resulting in a remainder of 589.
The number 3 becomes the next digit in our result. 
Result so far: 3984.12391573
If we subtract 2421 from 3010, we get 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

The final outcome is 3984.12391573, with a leftover of 5.89e-07.
