We're dividing 71520852 by 778 
Our goal is to divide 71520852 by 778.

Step 1:
778 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 778

Advancing to step 2:
The number 778 fits into 71 0 times, leaving a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 778

Let's proceed to step 3:
The number 778 fits into 715 0 times, leaving a remainder of 715.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 715 leaves us with 715.
Bring next digit (2) of the dividend behind the 715 and repeat the process: 7152 / 778

Going ahead to step 4:
778 goes into 7152 9 times with a remainder of 150.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 7002 away from 7152, we end up with 150.
Take the next digit (0) from the dividend and append it to 150, then repeat: 1500 / 778

Step 5:
If we divide 1500 by 778, we get 1 and a remainder of 722.
The next digit of our result is 1. 
Result so far: 91.0
Deduct 778 from 1500 and we're left with 722.
Bring next digit (8) of the dividend behind the 722 and repeat the process: 7228 / 778

Step 6:
The number 778 fits into 7228 9 times, leaving a remainder of 226.
Use 9 as the next digit of our solution. 
Result so far: 919.0
Subtract 7002 from 7228 to get 226.
Include the next digit (5) from the dividend after 226, then repeat: 2265 / 778

Advancing to step 7:
When dividing 2265 by 778, we get 2 with a remainder of 709.
The number 2 becomes the next digit in our result. 
Result so far: 9192.0
Subtracting 1556 from 2265 leaves us with 709.
Fetch the next digit (2) from the dividend, attach it to 709 and continue: 7092 / 778

On to step 8:
7092 divided by 778 is 9 with a remainder of 90.
The next digit of our result is 9. 
Result so far: 91929.0
Deduct 7002 from 7092 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 9:
900 divided by 778 is 1 with a remainder of 122.
Use 1 as the next digit of our solution. 
Result so far: 91929.1
The remainder is 122 after subtracting 778 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 10:
778 can be fit into 1220 1 times, resulting in a remainder of 442.
Use 1 as the next digit of our solution. 
Result so far: 91929.11
If we subtract 778 from 1220, we get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

The final result is 91929.11 with a remainder of 0.442.
