We're dividing 70595397 by 405 
Our goal is to divide 70595397 by 405.

Let's proceed to step 1:
If we divide 7 by 405, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 405

Moving on to step 2:
The number 405 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Take the next digit (5) from the dividend and append it to 70, then repeat: 705 / 405

On to step 3:
When dividing 705 by 405, we get 1 with a remainder of 300.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 300 after subtracting 405 from 705.
Append the next digit (9) from the dividend to 300 and continue with: 3009 / 405

Advancing to step 4:
405 goes into 3009 7 times with a remainder of 174.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 2835 away from 3009, we end up with 174.
Bring next digit (5) of the dividend behind the 174 and repeat the process: 1745 / 405

Step 5:
405 goes into 1745 4 times with a remainder of 125.
The next digit of our result is 4. 
Result so far: 174.0
Deduct 1620 from 1745 and we're left with 125.
Take the next digit (3) from the dividend and append it to 125, then repeat: 1253 / 405

Advancing to step 6:
405 goes into 1253 3 times with a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 1743.0
Deduct 1215 from 1253 and we're left with 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 405

Let's proceed to step 7:
389 divided by 405 is 0 with a remainder of 389.
Use 0 as the next digit of our solution. 
Result so far: 17430.0
Subtracting 0 from 389 leaves us with 389.
Include the next digit (7) from the dividend after 389, then repeat: 3897 / 405

Step 8:
The number 405 fits into 3897 9 times, leaving a remainder of 252.
Write down 9 as next digit of the result. 
Result so far: 174309.0
Deduct 3645 from 3897 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 9:
The number 405 fits into 2520 6 times, leaving a remainder of 90.
Put 6 as the next digit of the answer. 
Result so far: 174309.6
Subtracting 2430 from 2520 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 10:
When dividing 900 by 405, we get 2 with a remainder of 90.
Put 2 as the next digit of the answer. 
Result so far: 174309.62
The remainder is 90 after subtracting 810 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 11:
405 can be fit into 900 2 times, resulting in a remainder of 90.
Put 2 as the next digit of the answer. 
Result so far: 174309.622
Subtracting 810 from 900 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

After the division, we end up with 174309.622 and a remainder of 0.009.
