72308487 divided by 850 
We want to figure out the number of times 72308487 can be divided by 850.

Moving on to step 1:
850 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 850

Moving on to step 2:
850 goes into 72 0 times with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Grab the next digit (3) from the dividend, add it to 72, then carry on: 723 / 850

Moving on to step 3:
850 can be fit into 723 0 times, resulting in a remainder of 723.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 723 leaves us with 723.
Bring next digit (0) of the dividend behind the 723 and repeat the process: 7230 / 850

Advancing to step 4:
850 can be fit into 7230 8 times, resulting in a remainder of 430.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 430 after subtracting 6800 from 7230.
Take the next digit (8) from the dividend and append it to 430, then repeat: 4308 / 850

Let's proceed to step 5:
When dividing 4308 by 850, we get 5 with a remainder of 58.
Put 5 as the next digit of the answer. 
Result so far: 85.0
If we subtract 4250 from 4308, we get 58.
Bring next digit (4) of the dividend behind the 58 and repeat the process: 584 / 850

Moving on to step 6:
850 goes into 584 0 times with a remainder of 584.
Record the quotient 0 as the next digit in the result. 
Result so far: 850.0
Subtract 0 from 584 to get 584.
Take the next digit (8) from the dividend and append it to 584, then repeat: 5848 / 850

Step 7:
5848 divided by 850 is 6 with a remainder of 748.
Write down 6 as next digit of the result. 
Result so far: 8506.0
The remainder is 748 after subtracting 5100 from 5848.
Append the next digit (7) from the dividend to 748 and continue with: 7487 / 850

Moving on to step 8:
If we divide 7487 by 850, we get 8 and a remainder of 687.
Use 8 as the next digit of our solution. 
Result so far: 85068.0
If we take 6800 away from 7487, we end up with 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

On to step 9:
850 goes into 6870 8 times with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 85068.8
Deduct 6800 from 6870 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
The number 850 fits into 700 0 times, leaving a remainder of 700.
The next digit of our result is 0. 
Result so far: 85068.8
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 11:
If we divide 7000 by 850, we get 8 and a remainder of 200.
Use 8 as the next digit of our solution. 
Result so far: 85068.808
If we take 6800 away from 7000, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
The number 850 fits into 2000 2 times, leaving a remainder of 300.
Write down 2 as next digit of the result. 
Result so far: 85068.8082
Subtracting 1700 from 2000 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 13:
850 can be fit into 3000 3 times, resulting in a remainder of 450.
The number 3 becomes the next digit in our result. 
Result so far: 85068.80823
Subtract 2550 from 3000 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 14:
4500 divided by 850 is 5 with a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 85068.808235
Subtract 4250 from 4500 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 15:
If we divide 2500 by 850, we get 2 and a remainder of 800.
The next digit of our result is 2. 
Result so far: 85068.8082352
Subtracting 1700 from 2500 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Let's proceed to step 16:
8000 divided by 850 is 9 with a remainder of 350.
Record the quotient 9 as the next digit in the result. 
Result so far: 85068.80823529
The remainder is 350 after subtracting 7650 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

After the division, we end up with 85068.80823529 and a remainder of 3.5e-07.
