We're dividing 85436685 by 72 
We want to figure out the number of times 85436685 can be divided by 72.

Step 1:
8 divided by 72 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 72

On to step 2:
When dividing 85 by 72, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 72 from 85 to get 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 72

Advancing to step 3:
The number 72 fits into 134 1 times, leaving a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 72 from 134 leaves us with 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 72

Let's proceed to step 4:
72 can be fit into 623 8 times, resulting in a remainder of 47.
Write down 8 as next digit of the result. 
Result so far: 118.0
The remainder is 47 after subtracting 576 from 623.
Grab the next digit (6) from the dividend, add it to 47, then carry on: 476 / 72

Advancing to step 5:
When dividing 476 by 72, we get 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 1186.0
The remainder is 44 after subtracting 432 from 476.
Fetch the next digit (6) from the dividend, attach it to 44 and continue: 446 / 72

Step 6:
If we divide 446 by 72, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 11866.0
If we subtract 432 from 446, we get 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 72

Step 7:
148 divided by 72 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 118662.0
If we take 144 away from 148, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 72

Step 8:
45 divided by 72 is 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 1186620.0
Deduct 0 from 45 and we're left with 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:
450 divided by 72 is 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 1186620.6
Subtracting 432 from 450 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
180 divided by 72 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 1186620.62
If we take 144 away from 180, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
360 divided by 72 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1186620.625
If we take 360 away from 360, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
72 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1186620.625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
72 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1186620.625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 1186620.625 with a remainder of 0.0.
