Let's divide 31809094 by 905
Let's see how many times 905 fits into 31809094.

Going ahead to step 1:
905 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 905

Advancing to step 2:
31 divided by 905 is 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 905

Advancing to step 3:
If we divide 318 by 905, we get 0 and a remainder of 318.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 318 and we're left with 318.
Bring next digit (0) of the dividend behind the 318 and repeat the process: 3180 / 905

Going ahead to step 4:
When dividing 3180 by 905, we get 3 with a remainder of 465.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2715 from 3180 and we're left with 465.
Include the next digit (9) from the dividend after 465, then repeat: 4659 / 905

Advancing to step 5:
905 can be fit into 4659 5 times, resulting in a remainder of 134.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we take 4525 away from 4659, we end up with 134.
Bring next digit (0) of the dividend behind the 134 and repeat the process: 1340 / 905

On to step 6:
905 can be fit into 1340 1 times, resulting in a remainder of 435.
Write down 1 as next digit of the result. 
Result so far: 351.0
Subtracting 905 from 1340 leaves us with 435.
Fetch the next digit (9) from the dividend, attach it to 435 and continue: 4359 / 905

Advancing to step 7:
If we divide 4359 by 905, we get 4 and a remainder of 739.
Record the quotient 4 as the next digit in the result. 
Result so far: 3514.0
The remainder is 739 after subtracting 3620 from 4359.
Fetch the next digit (4) from the dividend, attach it to 739 and continue: 7394 / 905

Going ahead to step 8:
7394 divided by 905 is 8 with a remainder of 154.
The number 8 becomes the next digit in our result. 
Result so far: 35148.0
Subtract 7240 from 7394 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 9:
905 can be fit into 1540 1 times, resulting in a remainder of 635.
Use 1 as the next digit of our solution. 
Result so far: 35148.1
Deduct 905 from 1540 and we're left with 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Step 10:
When dividing 6350 by 905, we get 7 with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 35148.17
The remainder is 15 after subtracting 6335 from 6350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
When dividing 150 by 905, we get 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 35148.17
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 12:
If we divide 1500 by 905, we get 1 and a remainder of 595.
Use 1 as the next digit of our solution. 
Result so far: 35148.1701
Subtract 905 from 1500 to get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Advancing to step 13:
If we divide 5950 by 905, we get 6 and a remainder of 520.
Write down 6 as next digit of the result. 
Result so far: 35148.17016
Subtracting 5430 from 5950 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 14:
When dividing 5200 by 905, we get 5 with a remainder of 675.
Write down 5 as next digit of the result. 
Result so far: 35148.170165
Subtract 4525 from 5200 to get 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

On to step 15:
The number 905 fits into 6750 7 times, leaving a remainder of 415.
The next digit of our result is 7. 
Result so far: 35148.1701657
Deduct 6335 from 6750 and we're left with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Advancing to step 16:
4150 divided by 905 is 4 with a remainder of 530.
Use 4 as the next digit of our solution. 
Result so far: 35148.17016574
The remainder is 530 after subtracting 3620 from 4150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

The final result is 35148.17016574 with a remainder of 5.3e-07.
