Let's divide 3572390 by 685
We want to figure out the number of times 3572390 can be divided by 685.

Advancing to step 1:
685 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 685

Going ahead to step 2:
35 divided by 685 is 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 685

Step 3:
685 goes into 357 0 times with a remainder of 357.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 357 and we're left with 357.
Take the next digit (2) from the dividend and append it to 357, then repeat: 3572 / 685

On to step 4:
685 can be fit into 3572 5 times, resulting in a remainder of 147.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 3425 from 3572, we get 147.
Fetch the next digit (3) from the dividend, attach it to 147 and continue: 1473 / 685

Let's proceed to step 5:
1473 divided by 685 is 2 with a remainder of 103.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Subtracting 1370 from 1473 leaves us with 103.
Append the next digit (9) from the dividend to 103 and continue with: 1039 / 685

On to step 6:
The number 685 fits into 1039 1 times, leaving a remainder of 354.
Write down 1 as next digit of the result. 
Result so far: 521.0
If we take 685 away from 1039, we end up with 354.
Include the next digit (0) from the dividend after 354, then repeat: 3540 / 685

Moving on to step 7:
3540 divided by 685 is 5 with a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 5215.0
The remainder is 115 after subtracting 3425 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 8:
When dividing 1150 by 685, we get 1 with a remainder of 465.
The number 1 becomes the next digit in our result. 
Result so far: 5215.1
Deduct 685 from 1150 and we're left with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Going ahead to step 9:
685 goes into 4650 6 times with a remainder of 540.
The number 6 becomes the next digit in our result. 
Result so far: 5215.16
Subtract 4110 from 4650 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 10:
685 can be fit into 5400 7 times, resulting in a remainder of 605.
Put 7 as the next digit of the answer. 
Result so far: 5215.167
The remainder is 605 after subtracting 4795 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

On to step 11:
685 goes into 6050 8 times with a remainder of 570.
Use 8 as the next digit of our solution. 
Result so far: 5215.1678
If we subtract 5480 from 6050, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 12:
5700 divided by 685 is 8 with a remainder of 220.
Put 8 as the next digit of the answer. 
Result so far: 5215.16788
Subtract 5480 from 5700 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

The final outcome is 5215.16788, with a leftover of 0.00022.
