34549871 ÷ 321 
We want to divide 34549871 by 321.

On to step 1:
3 divided by 321 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 321

Moving on to step 2:
321 goes into 34 0 times with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 321

On to step 3:
321 can be fit into 345 1 times, resulting in a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 321 from 345, we get 24.
Take the next digit (4) from the dividend and append it to 24, then repeat: 244 / 321

Step 4:
244 divided by 321 is 0 with a remainder of 244.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 244 and we're left with 244.
Take the next digit (9) from the dividend and append it to 244, then repeat: 2449 / 321

Let's proceed to step 5:
When dividing 2449 by 321, we get 7 with a remainder of 202.
Write down 7 as next digit of the result. 
Result so far: 107.0
Subtracting 2247 from 2449 leaves us with 202.
Grab the next digit (8) from the dividend, add it to 202, then carry on: 2028 / 321

Advancing to step 6:
321 can be fit into 2028 6 times, resulting in a remainder of 102.
The next digit of our result is 6. 
Result so far: 1076.0
If we subtract 1926 from 2028, we get 102.
Fetch the next digit (7) from the dividend, attach it to 102 and continue: 1027 / 321

Moving on to step 7:
When dividing 1027 by 321, we get 3 with a remainder of 64.
Record the quotient 3 as the next digit in the result. 
Result so far: 10763.0
The remainder is 64 after subtracting 963 from 1027.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 321

Moving on to step 8:
When dividing 641 by 321, we get 1 with a remainder of 320.
The number 1 becomes the next digit in our result. 
Result so far: 107631.0
Subtracting 321 from 641 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 9:
3200 divided by 321 is 9 with a remainder of 311.
The number 9 becomes the next digit in our result. 
Result so far: 107631.9
If we subtract 2889 from 3200, we get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Step 10:
3110 divided by 321 is 9 with a remainder of 221.
Put 9 as the next digit of the answer. 
Result so far: 107631.99
Deduct 2889 from 3110 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

The quotient of the division is 107631.99, and the remainder is 0.221.
