Let's divide 3420575 by 905
We want to figure out the number of times 3420575 can be divided by 905.

Let's proceed to step 1:
When dividing 3 by 905, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 905

Going ahead to step 2:
34 divided by 905 is 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 905

Going ahead to step 3:
The number 905 fits into 342 0 times, leaving a remainder of 342.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 342 to get 342.
Bring next digit (0) of the dividend behind the 342 and repeat the process: 3420 / 905

Let's proceed to step 4:
The number 905 fits into 3420 3 times, leaving a remainder of 705.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 2715 from 3420 and we're left with 705.
Grab the next digit (5) from the dividend, add it to 705, then carry on: 7055 / 905

Step 5:
905 goes into 7055 7 times with a remainder of 720.
The next digit of our result is 7. 
Result so far: 37.0
Subtracting 6335 from 7055 leaves us with 720.
Fetch the next digit (7) from the dividend, attach it to 720 and continue: 7207 / 905

Let's proceed to step 6:
905 goes into 7207 7 times with a remainder of 872.
Use 7 as the next digit of our solution. 
Result so far: 377.0
If we subtract 6335 from 7207, we get 872.
Bring next digit (5) of the dividend behind the 872 and repeat the process: 8725 / 905

Step 7:
905 goes into 8725 9 times with a remainder of 580.
The number 9 becomes the next digit in our result. 
Result so far: 3779.0
If we take 8145 away from 8725, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

On to step 8:
5800 divided by 905 is 6 with a remainder of 370.
The next digit of our result is 6. 
Result so far: 3779.6
Subtract 5430 from 5800 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 9:
905 can be fit into 3700 4 times, resulting in a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 3779.64
The remainder is 80 after subtracting 3620 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
905 can be fit into 800 0 times, resulting in a remainder of 800.
Write down 0 as next digit of the result. 
Result so far: 3779.64
Deduct 0 from 800 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 11:
8000 divided by 905 is 8 with a remainder of 760.
Record the quotient 8 as the next digit in the result. 
Result so far: 3779.6408
Subtracting 7240 from 8000 leaves us with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Step 12:
905 goes into 7600 8 times with a remainder of 360.
The next digit of our result is 8. 
Result so far: 3779.64088
Subtract 7240 from 7600 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Our division results in 3779.64088 with a remaining 0.00036.
