87946313 divided by 720 
We want to figure out the number of times 87946313 can be divided by 720.

Step 1:
8 divided by 720 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 720

Advancing to step 2:
87 divided by 720 is 0 with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Include the next digit (9) from the dividend after 87, then repeat: 879 / 720

Step 3:
When dividing 879 by 720, we get 1 with a remainder of 159.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 720 from 879 leaves us with 159.
Append the next digit (4) from the dividend to 159 and continue with: 1594 / 720

On to step 4:
The number 720 fits into 1594 2 times, leaving a remainder of 154.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1440 from 1594 to get 154.
Fetch the next digit (6) from the dividend, attach it to 154 and continue: 1546 / 720

Moving on to step 5:
720 goes into 1546 2 times with a remainder of 106.
The next digit of our result is 2. 
Result so far: 122.0
Subtract 1440 from 1546 to get 106.
Grab the next digit (3) from the dividend, add it to 106, then carry on: 1063 / 720

Step 6:
1063 divided by 720 is 1 with a remainder of 343.
Write down 1 as next digit of the result. 
Result so far: 1221.0
Subtracting 720 from 1063 leaves us with 343.
Grab the next digit (1) from the dividend, add it to 343, then carry on: 3431 / 720

Moving on to step 7:
The number 720 fits into 3431 4 times, leaving a remainder of 551.
Record the quotient 4 as the next digit in the result. 
Result so far: 12214.0
Subtract 2880 from 3431 to get 551.
Fetch the next digit (3) from the dividend, attach it to 551 and continue: 5513 / 720

Let's proceed to step 8:
720 can be fit into 5513 7 times, resulting in a remainder of 473.
The next digit of our result is 7. 
Result so far: 122147.0
The remainder is 473 after subtracting 5040 from 5513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Advancing to step 9:
720 can be fit into 4730 6 times, resulting in a remainder of 410.
Use 6 as the next digit of our solution. 
Result so far: 122147.6
Deduct 4320 from 4730 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 10:
720 goes into 4100 5 times with a remainder of 500.
Put 5 as the next digit of the answer. 
Result so far: 122147.65
Subtract 3600 from 4100 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 11:
5000 divided by 720 is 6 with a remainder of 680.
The next digit of our result is 6. 
Result so far: 122147.656
Deduct 4320 from 5000 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 12:
If we divide 6800 by 720, we get 9 and a remainder of 320.
Use 9 as the next digit of our solution. 
Result so far: 122147.6569
If we take 6480 away from 6800, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 13:
When dividing 3200 by 720, we get 4 with a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 122147.65694
Subtract 2880 from 3200 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 14:
When dividing 3200 by 720, we get 4 with a remainder of 320.
The next digit of our result is 4. 
Result so far: 122147.656944
Subtracting 2880 from 3200 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Our division results in 122147.656944 with a remaining 3.2e-05.
