We divide 90426460 by 144
Our goal is to divide 90426460 by 144.

Advancing to step 1:
The number 144 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 144

Going ahead to step 2:
144 goes into 90 0 times with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Fetch the next digit (4) from the dividend, attach it to 90 and continue: 904 / 144

On to step 3:
When dividing 904 by 144, we get 6 with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 864 from 904, we get 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 144

Step 4:
144 can be fit into 402 2 times, resulting in a remainder of 114.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
Subtracting 288 from 402 leaves us with 114.
Grab the next digit (6) from the dividend, add it to 114, then carry on: 1146 / 144

Moving on to step 5:
If we divide 1146 by 144, we get 7 and a remainder of 138.
The next digit of our result is 7. 
Result so far: 627.0
If we take 1008 away from 1146, we end up with 138.
Include the next digit (4) from the dividend after 138, then repeat: 1384 / 144

Step 6:
When dividing 1384 by 144, we get 9 with a remainder of 88.
Write down 9 as next digit of the result. 
Result so far: 6279.0
The remainder is 88 after subtracting 1296 from 1384.
Include the next digit (6) from the dividend after 88, then repeat: 886 / 144

Going ahead to step 7:
886 divided by 144 is 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 62796.0
Subtracting 864 from 886 leaves us with 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 144

Advancing to step 8:
220 divided by 144 is 1 with a remainder of 76.
The next digit of our result is 1. 
Result so far: 627961.0
Subtracting 144 from 220 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 9:
760 divided by 144 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 627961.5
If we subtract 720 from 760, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
400 divided by 144 is 2 with a remainder of 112.
Write down 2 as next digit of the result. 
Result so far: 627961.52
Subtracting 288 from 400 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 11:
If we divide 1120 by 144, we get 7 and a remainder of 112.
Put 7 as the next digit of the answer. 
Result so far: 627961.527
The remainder is 112 after subtracting 1008 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 12:
1120 divided by 144 is 7 with a remainder of 112.
The number 7 becomes the next digit in our result. 
Result so far: 627961.5277
Subtracting 1008 from 1120 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final outcome is 627961.5277, with a leftover of 0.00112.
