Let's divide 88171703 by 405
We want to divide 88171703 by 405.

On to step 1:
The number 405 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 405

Step 2:
If we divide 88 by 405, we get 0 and a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 88, we get 88.
Grab the next digit (1) from the dividend, add it to 88, then carry on: 881 / 405

Let's proceed to step 3:
The number 405 fits into 881 2 times, leaving a remainder of 71.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 810 from 881 leaves us with 71.
Fetch the next digit (7) from the dividend, attach it to 71 and continue: 717 / 405

Advancing to step 4:
The number 405 fits into 717 1 times, leaving a remainder of 312.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 405 from 717, we get 312.
Take the next digit (1) from the dividend and append it to 312, then repeat: 3121 / 405

On to step 5:
405 goes into 3121 7 times with a remainder of 286.
Use 7 as the next digit of our solution. 
Result so far: 217.0
Subtracting 2835 from 3121 leaves us with 286.
Fetch the next digit (7) from the dividend, attach it to 286 and continue: 2867 / 405

Let's proceed to step 6:
The number 405 fits into 2867 7 times, leaving a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 2177.0
Subtracting 2835 from 2867 leaves us with 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 405

Going ahead to step 7:
320 divided by 405 is 0 with a remainder of 320.
The next digit of our result is 0. 
Result so far: 21770.0
Subtracting 0 from 320 leaves us with 320.
Include the next digit (3) from the dividend after 320, then repeat: 3203 / 405

Advancing to step 8:
If we divide 3203 by 405, we get 7 and a remainder of 368.
Use 7 as the next digit of our solution. 
Result so far: 217707.0
Deduct 2835 from 3203 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 9:
The number 405 fits into 3680 9 times, leaving a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 217707.9
Deduct 3645 from 3680 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
405 goes into 350 0 times with a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 217707.9
Subtracting 0 from 350 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 11:
If we divide 3500 by 405, we get 8 and a remainder of 260.
Record the quotient 8 as the next digit in the result. 
Result so far: 217707.908
The remainder is 260 after subtracting 3240 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 12:
The number 405 fits into 2600 6 times, leaving a remainder of 170.
Put 6 as the next digit of the answer. 
Result so far: 217707.9086
If we take 2430 away from 2600, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 13:
When dividing 1700 by 405, we get 4 with a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 217707.90864
The remainder is 80 after subtracting 1620 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
The number 405 fits into 800 1 times, leaving a remainder of 395.
Write down 1 as next digit of the result. 
Result so far: 217707.908641
Deduct 405 from 800 and we're left with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

On to step 15:
3950 divided by 405 is 9 with a remainder of 305.
Write down 9 as next digit of the result. 
Result so far: 217707.9086419
If we take 3645 away from 3950, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Let's proceed to step 16:
405 goes into 3050 7 times with a remainder of 215.
The number 7 becomes the next digit in our result. 
Result so far: 217707.90864197
The remainder is 215 after subtracting 2835 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Our division results in 217707.90864197 with a remaining 2.15e-07.
