63261165 ÷ 434 
We want to divide 63261165 by 434.

Step 1:
434 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 434

Moving on to step 2:
The number 434 fits into 63 0 times, leaving a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Append the next digit (2) from the dividend to 63 and continue with: 632 / 434

On to step 3:
434 goes into 632 1 times with a remainder of 198.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 198 after subtracting 434 from 632.
Fetch the next digit (6) from the dividend, attach it to 198 and continue: 1986 / 434

Advancing to step 4:
If we divide 1986 by 434, we get 4 and a remainder of 250.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 250 after subtracting 1736 from 1986.
Grab the next digit (1) from the dividend, add it to 250, then carry on: 2501 / 434

Going ahead to step 5:
If we divide 2501 by 434, we get 5 and a remainder of 331.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
Subtracting 2170 from 2501 leaves us with 331.
Take the next digit (1) from the dividend and append it to 331, then repeat: 3311 / 434

Advancing to step 6:
If we divide 3311 by 434, we get 7 and a remainder of 273.
Record the quotient 7 as the next digit in the result. 
Result so far: 1457.0
The remainder is 273 after subtracting 3038 from 3311.
Take the next digit (6) from the dividend and append it to 273, then repeat: 2736 / 434

Step 7:
434 can be fit into 2736 6 times, resulting in a remainder of 132.
The number 6 becomes the next digit in our result. 
Result so far: 14576.0
Deduct 2604 from 2736 and we're left with 132.
Grab the next digit (5) from the dividend, add it to 132, then carry on: 1325 / 434

Step 8:
434 can be fit into 1325 3 times, resulting in a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 145763.0
Deduct 1302 from 1325 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
If we divide 230 by 434, we get 0 and a remainder of 230.
Use 0 as the next digit of our solution. 
Result so far: 145763.0
Subtracting 0 from 230 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 10:
If we divide 2300 by 434, we get 5 and a remainder of 130.
Record the quotient 5 as the next digit in the result. 
Result so far: 145763.05
Subtracting 2170 from 2300 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 11:
434 can be fit into 1300 2 times, resulting in a remainder of 432.
Use 2 as the next digit of our solution. 
Result so far: 145763.052
If we take 868 away from 1300, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 12:
4320 divided by 434 is 9 with a remainder of 414.
Use 9 as the next digit of our solution. 
Result so far: 145763.0529
If we take 3906 away from 4320, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 13:
434 can be fit into 4140 9 times, resulting in a remainder of 234.
Write down 9 as next digit of the result. 
Result so far: 145763.05299
If we subtract 3906 from 4140, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

The final result is 145763.05299 with a remainder of 0.000234.
