Let's divide 603523 by 70
Our goal is to divide 603523 by 70.

On to step 1:
If we divide 6 by 70, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 70

On to step 2:
When dividing 60 by 70, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 70

Going ahead to step 3:
70 can be fit into 603 8 times, resulting in a remainder of 43.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 560 from 603 and we're left with 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 70

On to step 4:
70 goes into 435 6 times with a remainder of 15.
The next digit of our result is 6. 
Result so far: 86.0
If we subtract 420 from 435, we get 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 70

On to step 5:
70 goes into 152 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 862.0
Deduct 140 from 152 and we're left with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 70

Moving on to step 6:
123 divided by 70 is 1 with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 8621.0
Deduct 70 from 123 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 7:
When dividing 530 by 70, we get 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 8621.7
The remainder is 40 after subtracting 490 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
70 goes into 400 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 8621.75
If we subtract 350 from 400, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
The number 70 fits into 500 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 8621.757
Deduct 490 from 500 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
70 goes into 100 1 times with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 8621.7571
If we subtract 70 from 100, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 8621.75714
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 8621.757142
If we subtract 140 from 200, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
70 can be fit into 600 8 times, resulting in a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 8621.7571428
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
400 divided by 70 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 8621.75714285
If we take 350 away from 400, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 8621.75714285 and a remainder of 5e-08.
