72020618 ÷ 436 
Our goal is to divide 72020618 by 436.

Going ahead to step 1:
436 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 436

Step 2:
436 can be fit into 72 0 times, resulting in a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Grab the next digit (0) from the dividend, add it to 72, then carry on: 720 / 436

Advancing to step 3:
If we divide 720 by 436, we get 1 and a remainder of 284.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 436 from 720 and we're left with 284.
Bring next digit (2) of the dividend behind the 284 and repeat the process: 2842 / 436

Let's proceed to step 4:
When dividing 2842 by 436, we get 6 with a remainder of 226.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 2616 from 2842 and we're left with 226.
Fetch the next digit (0) from the dividend, attach it to 226 and continue: 2260 / 436

Let's proceed to step 5:
If we divide 2260 by 436, we get 5 and a remainder of 80.
The next digit of our result is 5. 
Result so far: 165.0
Deduct 2180 from 2260 and we're left with 80.
Append the next digit (6) from the dividend to 80 and continue with: 806 / 436

Moving on to step 6:
436 goes into 806 1 times with a remainder of 370.
Write down 1 as next digit of the result. 
Result so far: 1651.0
If we take 436 away from 806, we end up with 370.
Append the next digit (1) from the dividend to 370 and continue with: 3701 / 436

Advancing to step 7:
When dividing 3701 by 436, we get 8 with a remainder of 213.
Record the quotient 8 as the next digit in the result. 
Result so far: 16518.0
If we take 3488 away from 3701, we end up with 213.
Include the next digit (8) from the dividend after 213, then repeat: 2138 / 436

Advancing to step 8:
436 goes into 2138 4 times with a remainder of 394.
Put 4 as the next digit of the answer. 
Result so far: 165184.0
If we subtract 1744 from 2138, we get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 9:
3940 divided by 436 is 9 with a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 165184.9
Deduct 3924 from 3940 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
If we divide 160 by 436, we get 0 and a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 165184.9
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 11:
436 can be fit into 1600 3 times, resulting in a remainder of 292.
The next digit of our result is 3. 
Result so far: 165184.903
If we subtract 1308 from 1600, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 12:
436 can be fit into 2920 6 times, resulting in a remainder of 304.
Put 6 as the next digit of the answer. 
Result so far: 165184.9036
Deduct 2616 from 2920 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 13:
When dividing 3040 by 436, we get 6 with a remainder of 424.
Record the quotient 6 as the next digit in the result. 
Result so far: 165184.90366
If we take 2616 away from 3040, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

The final result is 165184.90366 with a remainder of 0.000424.
