87023059 ÷ 720 
Our goal is to divide 87023059 by 720.

On to step 1:
If we divide 8 by 720, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 720

Going ahead to step 2:
87 divided by 720 is 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Bring next digit (0) of the dividend behind the 87 and repeat the process: 870 / 720

Going ahead to step 3:
720 goes into 870 1 times with a remainder of 150.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 720 away from 870, we end up with 150.
Include the next digit (2) from the dividend after 150, then repeat: 1502 / 720

Moving on to step 4:
When dividing 1502 by 720, we get 2 with a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1440 from 1502, we get 62.
Take the next digit (3) from the dividend and append it to 62, then repeat: 623 / 720

Advancing to step 5:
When dividing 623 by 720, we get 0 with a remainder of 623.
Write down 0 as next digit of the result. 
Result so far: 120.0
Subtract 0 from 623 to get 623.
Bring next digit (0) of the dividend behind the 623 and repeat the process: 6230 / 720

Advancing to step 6:
720 can be fit into 6230 8 times, resulting in a remainder of 470.
The number 8 becomes the next digit in our result. 
Result so far: 1208.0
Deduct 5760 from 6230 and we're left with 470.
Fetch the next digit (5) from the dividend, attach it to 470 and continue: 4705 / 720

Advancing to step 7:
720 can be fit into 4705 6 times, resulting in a remainder of 385.
Use 6 as the next digit of our solution. 
Result so far: 12086.0
Subtracting 4320 from 4705 leaves us with 385.
Bring next digit (9) of the dividend behind the 385 and repeat the process: 3859 / 720

Going ahead to step 8:
720 goes into 3859 5 times with a remainder of 259.
Use 5 as the next digit of our solution. 
Result so far: 120865.0
If we subtract 3600 from 3859, we get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Going ahead to step 9:
When dividing 2590 by 720, we get 3 with a remainder of 430.
Put 3 as the next digit of the answer. 
Result so far: 120865.3
Subtracting 2160 from 2590 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 10:
4300 divided by 720 is 5 with a remainder of 700.
The next digit of our result is 5. 
Result so far: 120865.35
Subtract 3600 from 4300 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 11:
720 can be fit into 7000 9 times, resulting in a remainder of 520.
Write down 9 as next digit of the result. 
Result so far: 120865.359
If we subtract 6480 from 7000, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 12:
The number 720 fits into 5200 7 times, leaving a remainder of 160.
The number 7 becomes the next digit in our result. 
Result so far: 120865.3597
If we subtract 5040 from 5200, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
1600 divided by 720 is 2 with a remainder of 160.
Write down 2 as next digit of the result. 
Result so far: 120865.35972
Subtracting 1440 from 1600 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 14:
The number 720 fits into 1600 2 times, leaving a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 120865.359722
Subtracting 1440 from 1600 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 120865.359722, with a leftover of 1.6e-05.
