353603 divided by 85 
We want to figure out the number of times 353603 can be divided by 85.

Advancing to step 1:
If we divide 3 by 85, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 85

Let's proceed to step 2:
If we divide 35 by 85, we get 0 and a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 85

Going ahead to step 3:
353 divided by 85 is 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 340 from 353 and we're left with 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 85

Going ahead to step 4:
85 can be fit into 136 1 times, resulting in a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
If we subtract 85 from 136, we get 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 85

Step 5:
85 goes into 510 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 416.0
Deduct 510 from 510 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 85

Going ahead to step 6:
3 divided by 85 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 4160.0
If we take 0 away from 3, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
85 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 4160.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
85 goes into 300 3 times with a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 4160.03
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
85 goes into 450 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 4160.035
If we take 425 away from 450, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
When dividing 250 by 85, we get 2 with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 4160.0352
Subtracting 170 from 250 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
When dividing 800 by 85, we get 9 with a remainder of 35.
The next digit of our result is 9. 
Result so far: 4160.03529
Subtract 765 from 800 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
350 divided by 85 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 4160.035294
The remainder is 10 after subtracting 340 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
When dividing 100 by 85, we get 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 4160.0352941
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 14:
85 goes into 150 1 times with a remainder of 65.
The next digit of our result is 1. 
Result so far: 4160.03529411
Deduct 85 from 150 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 4160.03529411, and the remainder is 6.5e-08.
