61685346 ÷ 72 
Let's see how many times 72 fits into 61685346.

On to step 1:
The number 72 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 72

Step 2:
72 can be fit into 61 0 times, resulting in a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 61 to get 61.
Fetch the next digit (6) from the dividend, attach it to 61 and continue: 616 / 72

Let's proceed to step 3:
If we divide 616 by 72, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 576 from 616 to get 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 72

Advancing to step 4:
The number 72 fits into 408 5 times, leaving a remainder of 48.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we subtract 360 from 408, we get 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 72

Step 5:
72 can be fit into 485 6 times, resulting in a remainder of 53.
The next digit of our result is 6. 
Result so far: 856.0
If we take 432 away from 485, we end up with 53.
Grab the next digit (3) from the dividend, add it to 53, then carry on: 533 / 72

Moving on to step 6:
If we divide 533 by 72, we get 7 and a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 8567.0
Subtract 504 from 533 to get 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 72

On to step 7:
72 goes into 294 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 85674.0
If we subtract 288 from 294, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 72

Going ahead to step 8:
72 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 856740.0
Subtract 0 from 66 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
660 divided by 72 is 9 with a remainder of 12.
The next digit of our result is 9. 
Result so far: 856740.9
If we subtract 648 from 660, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
120 divided by 72 is 1 with a remainder of 48.
The next digit of our result is 1. 
Result so far: 856740.91
Deduct 72 from 120 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
The number 72 fits into 480 6 times, leaving a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 856740.916
If we take 432 away from 480, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
72 goes into 480 6 times with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 856740.9166
Deduct 432 from 480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 856740.9166 with a remainder of 0.00048.
