40290145 divided by 93 
We want to figure out the number of times 40290145 can be divided by 93.

On to step 1:
4 divided by 93 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 93

Going ahead to step 2:
When dividing 40 by 93, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 93

On to step 3:
93 goes into 402 4 times with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 372 from 402 leaves us with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 93

Let's proceed to step 4:
The number 93 fits into 309 3 times, leaving a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 279 from 309 leaves us with 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 93

Step 5:
If we divide 300 by 93, we get 3 and a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 433.0
Deduct 279 from 300 and we're left with 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 93

On to step 6:
When dividing 211 by 93, we get 2 with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 4332.0
Subtracting 186 from 211 leaves us with 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 93

Let's proceed to step 7:
The number 93 fits into 254 2 times, leaving a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 43322.0
If we subtract 186 from 254, we get 68.
Take the next digit (5) from the dividend and append it to 68, then repeat: 685 / 93

On to step 8:
93 goes into 685 7 times with a remainder of 34.
The next digit of our result is 7. 
Result so far: 433227.0
Subtract 651 from 685 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
If we divide 340 by 93, we get 3 and a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 433227.3
Deduct 279 from 340 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 10:
The number 93 fits into 610 6 times, leaving a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 433227.36
If we take 558 away from 610, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
If we divide 520 by 93, we get 5 and a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 433227.365
If we subtract 465 from 520, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 12:
93 can be fit into 550 5 times, resulting in a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 433227.3655
If we take 465 away from 550, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Our division results in 433227.3655 with a remaining 0.00085.
