We're dividing 11772791 by 145 
We want to divide 11772791 by 145.

Going ahead to step 1:
When dividing 1 by 145, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 145

Advancing to step 2:
145 can be fit into 11 0 times, resulting in a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 145

Advancing to step 3:
145 can be fit into 117 0 times, resulting in a remainder of 117.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 117 leaves us with 117.
Take the next digit (7) from the dividend and append it to 117, then repeat: 1177 / 145

Let's proceed to step 4:
1177 divided by 145 is 8 with a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 1160 from 1177, we get 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 145

Going ahead to step 5:
The number 145 fits into 172 1 times, leaving a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 81.0
If we take 145 away from 172, we end up with 27.
Include the next digit (7) from the dividend after 27, then repeat: 277 / 145

Step 6:
If we divide 277 by 145, we get 1 and a remainder of 132.
Use 1 as the next digit of our solution. 
Result so far: 811.0
Subtract 145 from 277 to get 132.
Grab the next digit (9) from the dividend, add it to 132, then carry on: 1329 / 145

Going ahead to step 7:
If we divide 1329 by 145, we get 9 and a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 8119.0
If we subtract 1305 from 1329, we get 24.
Bring next digit (1) of the dividend behind the 24 and repeat the process: 241 / 145

Advancing to step 8:
145 goes into 241 1 times with a remainder of 96.
The next digit of our result is 1. 
Result so far: 81191.0
Deduct 145 from 241 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 9:
The number 145 fits into 960 6 times, leaving a remainder of 90.
Use 6 as the next digit of our solution. 
Result so far: 81191.6
If we subtract 870 from 960, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
145 goes into 900 6 times with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 81191.66
Subtracting 870 from 900 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 81191.66 with a remainder of 0.03.
