31645034 ÷ 434 
We want to divide 31645034 by 434.

On to step 1:
The number 434 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 434

Step 2:
434 can be fit into 31 0 times, resulting in a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 434

Let's proceed to step 3:
316 divided by 434 is 0 with a remainder of 316.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 316 to get 316.
Include the next digit (4) from the dividend after 316, then repeat: 3164 / 434

Advancing to step 4:
3164 divided by 434 is 7 with a remainder of 126.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 3038 from 3164 leaves us with 126.
Bring next digit (5) of the dividend behind the 126 and repeat the process: 1265 / 434

On to step 5:
1265 divided by 434 is 2 with a remainder of 397.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Deduct 868 from 1265 and we're left with 397.
Append the next digit (0) from the dividend to 397 and continue with: 3970 / 434

Moving on to step 6:
434 can be fit into 3970 9 times, resulting in a remainder of 64.
The next digit of our result is 9. 
Result so far: 729.0
If we subtract 3906 from 3970, we get 64.
Append the next digit (3) from the dividend to 64 and continue with: 643 / 434

Advancing to step 7:
The number 434 fits into 643 1 times, leaving a remainder of 209.
Use 1 as the next digit of our solution. 
Result so far: 7291.0
If we take 434 away from 643, we end up with 209.
Append the next digit (4) from the dividend to 209 and continue with: 2094 / 434

On to step 8:
The number 434 fits into 2094 4 times, leaving a remainder of 358.
Use 4 as the next digit of our solution. 
Result so far: 72914.0
If we subtract 1736 from 2094, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Step 9:
3580 divided by 434 is 8 with a remainder of 108.
The next digit of our result is 8. 
Result so far: 72914.8
Subtract 3472 from 3580 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 10:
434 goes into 1080 2 times with a remainder of 212.
Put 2 as the next digit of the answer. 
Result so far: 72914.82
Deduct 868 from 1080 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 11:
434 can be fit into 2120 4 times, resulting in a remainder of 384.
The next digit of our result is 4. 
Result so far: 72914.824
If we take 1736 away from 2120, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 12:
When dividing 3840 by 434, we get 8 with a remainder of 368.
Record the quotient 8 as the next digit in the result. 
Result so far: 72914.8248
Subtract 3472 from 3840 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 13:
When dividing 3680 by 434, we get 8 with a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 72914.82488
If we subtract 3472 from 3680, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

After the division, we end up with 72914.82488 and a remainder of 0.000208.
