72946210 ÷ 325 
We want to figure out the number of times 72946210 can be divided by 325.

On to step 1:
If we divide 7 by 325, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 325

Going ahead to step 2:
If we divide 72 by 325, we get 0 and a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Bring next digit (9) of the dividend behind the 72 and repeat the process: 729 / 325

On to step 3:
The number 325 fits into 729 2 times, leaving a remainder of 79.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 79 after subtracting 650 from 729.
Bring next digit (4) of the dividend behind the 79 and repeat the process: 794 / 325

Step 4:
325 can be fit into 794 2 times, resulting in a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 22.0
The remainder is 144 after subtracting 650 from 794.
Append the next digit (6) from the dividend to 144 and continue with: 1446 / 325

Advancing to step 5:
When dividing 1446 by 325, we get 4 with a remainder of 146.
The number 4 becomes the next digit in our result. 
Result so far: 224.0
Subtract 1300 from 1446 to get 146.
Grab the next digit (2) from the dividend, add it to 146, then carry on: 1462 / 325

On to step 6:
When dividing 1462 by 325, we get 4 with a remainder of 162.
The number 4 becomes the next digit in our result. 
Result so far: 2244.0
If we subtract 1300 from 1462, we get 162.
Grab the next digit (1) from the dividend, add it to 162, then carry on: 1621 / 325

On to step 7:
When dividing 1621 by 325, we get 4 with a remainder of 321.
The number 4 becomes the next digit in our result. 
Result so far: 22444.0
If we take 1300 away from 1621, we end up with 321.
Bring next digit (0) of the dividend behind the 321 and repeat the process: 3210 / 325

On to step 8:
When dividing 3210 by 325, we get 9 with a remainder of 285.
Record the quotient 9 as the next digit in the result. 
Result so far: 224449.0
Deduct 2925 from 3210 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 9:
When dividing 2850 by 325, we get 8 with a remainder of 250.
Use 8 as the next digit of our solution. 
Result so far: 224449.8
If we take 2600 away from 2850, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 10:
The number 325 fits into 2500 7 times, leaving a remainder of 225.
Write down 7 as next digit of the result. 
Result so far: 224449.87
The remainder is 225 after subtracting 2275 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 11:
325 can be fit into 2250 6 times, resulting in a remainder of 300.
Write down 6 as next digit of the result. 
Result so far: 224449.876
The remainder is 300 after subtracting 1950 from 2250.
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 12:
If we divide 3000 by 325, we get 9 and a remainder of 75.
Use 9 as the next digit of our solution. 
Result so far: 224449.8769
If we subtract 2925 from 3000, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 13:
If we divide 750 by 325, we get 2 and a remainder of 100.
Put 2 as the next digit of the answer. 
Result so far: 224449.87692
The remainder is 100 after subtracting 650 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 14:
The number 325 fits into 1000 3 times, leaving a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 224449.876923
Deduct 975 from 1000 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 15:
325 goes into 250 0 times with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 224449.876923
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 16:
325 goes into 2500 7 times with a remainder of 225.
Put 7 as the next digit of the answer. 
Result so far: 224449.87692307
If we take 2275 away from 2500, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

After the division, we end up with 224449.87692307 and a remainder of 2.25e-07.
