We look at the division of 11225915 by 143 
We want to divide 11225915 by 143.

On to step 1:
If we divide 1 by 143, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 143

On to step 2:
143 can be fit into 11 0 times, resulting in a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 143

Going ahead to step 3:
143 goes into 112 0 times with a remainder of 112.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 112 leaves us with 112.
Take the next digit (2) from the dividend and append it to 112, then repeat: 1122 / 143

Advancing to step 4:
143 can be fit into 1122 7 times, resulting in a remainder of 121.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 1001 from 1122 and we're left with 121.
Grab the next digit (5) from the dividend, add it to 121, then carry on: 1215 / 143

Advancing to step 5:
When dividing 1215 by 143, we get 8 with a remainder of 71.
The next digit of our result is 8. 
Result so far: 78.0
If we subtract 1144 from 1215, we get 71.
Include the next digit (9) from the dividend after 71, then repeat: 719 / 143

On to step 6:
When dividing 719 by 143, we get 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 785.0
Subtract 715 from 719 to get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 143

Moving on to step 7:
If we divide 41 by 143, we get 0 and a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 7850.0
The remainder is 41 after subtracting 0 from 41.
Append the next digit (5) from the dividend to 41 and continue with: 415 / 143

Let's proceed to step 8:
The number 143 fits into 415 2 times, leaving a remainder of 129.
The next digit of our result is 2. 
Result so far: 78502.0
Subtracting 286 from 415 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Advancing to step 9:
1290 divided by 143 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 78502.9
Subtract 1287 from 1290 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
30 divided by 143 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 78502.9
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
143 can be fit into 300 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 78502.902
Subtract 286 from 300 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
If we divide 140 by 143, we get 0 and a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 78502.902
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 13:
If we divide 1400 by 143, we get 9 and a remainder of 113.
Write down 9 as next digit of the result. 
Result so far: 78502.90209
The remainder is 113 after subtracting 1287 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 14:
143 can be fit into 1130 7 times, resulting in a remainder of 129.
Write down 7 as next digit of the result. 
Result so far: 78502.902097
Subtracting 1001 from 1130 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 15:
143 can be fit into 1290 9 times, resulting in a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 78502.9020979
If we subtract 1287 from 1290, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 16:
30 divided by 143 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 78502.9020979
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 78502.9020979 and a remainder of 3e-08.
