Let's divide 89270287 by 405
We want to figure out the number of times 89270287 can be divided by 405.

Advancing to step 1:
If we divide 8 by 405, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 405

Advancing to step 2:
405 goes into 89 0 times with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Take the next digit (2) from the dividend and append it to 89, then repeat: 892 / 405

Let's proceed to step 3:
405 can be fit into 892 2 times, resulting in a remainder of 82.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 82 after subtracting 810 from 892.
Append the next digit (7) from the dividend to 82 and continue with: 827 / 405

Let's proceed to step 4:
If we divide 827 by 405, we get 2 and a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we subtract 810 from 827, we get 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 405

Going ahead to step 5:
405 can be fit into 170 0 times, resulting in a remainder of 170.
The next digit of our result is 0. 
Result so far: 220.0
The remainder is 170 after subtracting 0 from 170.
Append the next digit (2) from the dividend to 170 and continue with: 1702 / 405

Advancing to step 6:
405 can be fit into 1702 4 times, resulting in a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 2204.0
If we subtract 1620 from 1702, we get 82.
Fetch the next digit (8) from the dividend, attach it to 82 and continue: 828 / 405

Step 7:
405 can be fit into 828 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 22042.0
If we subtract 810 from 828, we get 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 405

Advancing to step 8:
187 divided by 405 is 0 with a remainder of 187.
Use 0 as the next digit of our solution. 
Result so far: 220420.0
If we take 0 away from 187, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Step 9:
The number 405 fits into 1870 4 times, leaving a remainder of 250.
Write down 4 as next digit of the result. 
Result so far: 220420.4
Subtracting 1620 from 1870 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 10:
When dividing 2500 by 405, we get 6 with a remainder of 70.
The next digit of our result is 6. 
Result so far: 220420.46
The remainder is 70 after subtracting 2430 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
If we divide 700 by 405, we get 1 and a remainder of 295.
The next digit of our result is 1. 
Result so far: 220420.461
If we subtract 405 from 700, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 12:
405 can be fit into 2950 7 times, resulting in a remainder of 115.
Put 7 as the next digit of the answer. 
Result so far: 220420.4617
Subtracting 2835 from 2950 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 13:
1150 divided by 405 is 2 with a remainder of 340.
The next digit of our result is 2. 
Result so far: 220420.46172
Deduct 810 from 1150 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 14:
When dividing 3400 by 405, we get 8 with a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 220420.461728
The remainder is 160 after subtracting 3240 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 15:
If we divide 1600 by 405, we get 3 and a remainder of 385.
Write down 3 as next digit of the result. 
Result so far: 220420.4617283
Subtract 1215 from 1600 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 16:
If we divide 3850 by 405, we get 9 and a remainder of 205.
Record the quotient 9 as the next digit in the result. 
Result so far: 220420.46172839
Subtracting 3645 from 3850 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

The final result is 220420.46172839 with a remainder of 2.05e-07.
