Let's divide 31521430 by 905
We're looking to find how many times 905 goes into 31521430.

Let's proceed to step 1:
905 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 905

Moving on to step 2:
When dividing 31 by 905, we get 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 905

Let's proceed to step 3:
If we divide 315 by 905, we get 0 and a remainder of 315.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 315 after subtracting 0 from 315.
Grab the next digit (2) from the dividend, add it to 315, then carry on: 3152 / 905

Step 4:
905 goes into 3152 3 times with a remainder of 437.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 2715 from 3152, we get 437.
Append the next digit (1) from the dividend to 437 and continue with: 4371 / 905

Going ahead to step 5:
If we divide 4371 by 905, we get 4 and a remainder of 751.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtract 3620 from 4371 to get 751.
Take the next digit (4) from the dividend and append it to 751, then repeat: 7514 / 905

Let's proceed to step 6:
905 goes into 7514 8 times with a remainder of 274.
Write down 8 as next digit of the result. 
Result so far: 348.0
Deduct 7240 from 7514 and we're left with 274.
Bring next digit (3) of the dividend behind the 274 and repeat the process: 2743 / 905

Advancing to step 7:
The number 905 fits into 2743 3 times, leaving a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 3483.0
If we take 2715 away from 2743, we end up with 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 905

Let's proceed to step 8:
280 divided by 905 is 0 with a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 34830.0
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 9:
905 can be fit into 2800 3 times, resulting in a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 34830.3
If we take 2715 away from 2800, 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.

Going ahead to step 10:
905 can be fit into 850 0 times, resulting in a remainder of 850.
The number 0 becomes the next digit in our result. 
Result so far: 34830.3
Subtracting 0 from 850 leaves us with 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

On to step 11:
905 goes into 8500 9 times with a remainder of 355.
The number 9 becomes the next digit in our result. 
Result so far: 34830.309
Subtracting 8145 from 8500 leaves us with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 12:
When dividing 3550 by 905, we get 3 with a remainder of 835.
Put 3 as the next digit of the answer. 
Result so far: 34830.3093
Deduct 2715 from 3550 and we're left with 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Advancing to step 13:
When dividing 8350 by 905, we get 9 with a remainder of 205.
Use 9 as the next digit of our solution. 
Result so far: 34830.30939
Subtracting 8145 from 8350 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.

Moving on to step 14:
If we divide 2050 by 905, we get 2 and a remainder of 240.
Record the quotient 2 as the next digit in the result. 
Result so far: 34830.309392
If we subtract 1810 from 2050, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 15:
905 goes into 2400 2 times with a remainder of 590.
Use 2 as the next digit of our solution. 
Result so far: 34830.3093922
Subtracting 1810 from 2400 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

After the division, we end up with 34830.3093922 and a remainder of 5.9e-06.
