64521628 ÷ 634 
Let's see how many times 634 fits into 64521628.

Advancing to step 1:
If we divide 6 by 634, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 634

Step 2:
64 divided by 634 is 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Fetch the next digit (5) from the dividend, attach it to 64 and continue: 645 / 634

Advancing to step 3:
The number 634 fits into 645 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 634 away from 645, we end up with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 634

Step 4:
If we divide 112 by 634, we get 0 and a remainder of 112.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 112 leaves us with 112.
Bring next digit (1) of the dividend behind the 112 and repeat the process: 1121 / 634

Going ahead to step 5:
The number 634 fits into 1121 1 times, leaving a remainder of 487.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Deduct 634 from 1121 and we're left with 487.
Take the next digit (6) from the dividend and append it to 487, then repeat: 4876 / 634

On to step 6:
634 can be fit into 4876 7 times, resulting in a remainder of 438.
The next digit of our result is 7. 
Result so far: 1017.0
Deduct 4438 from 4876 and we're left with 438.
Grab the next digit (2) from the dividend, add it to 438, then carry on: 4382 / 634

Moving on to step 7:
If we divide 4382 by 634, we get 6 and a remainder of 578.
Put 6 as the next digit of the answer. 
Result so far: 10176.0
If we subtract 3804 from 4382, we get 578.
Fetch the next digit (8) from the dividend, attach it to 578 and continue: 5788 / 634

Going ahead to step 8:
634 goes into 5788 9 times with a remainder of 82.
The next digit of our result is 9. 
Result so far: 101769.0
Subtract 5706 from 5788 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 9:
634 can be fit into 820 1 times, resulting in a remainder of 186.
The number 1 becomes the next digit in our result. 
Result so far: 101769.1
If we subtract 634 from 820, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 10:
634 goes into 1860 2 times with a remainder of 592.
The number 2 becomes the next digit in our result. 
Result so far: 101769.12
If we subtract 1268 from 1860, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Step 11:
634 can be fit into 5920 9 times, resulting in a remainder of 214.
Record the quotient 9 as the next digit in the result. 
Result so far: 101769.129
If we subtract 5706 from 5920, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 12:
If we divide 2140 by 634, we get 3 and a remainder of 238.
Record the quotient 3 as the next digit in the result. 
Result so far: 101769.1293
If we take 1902 away from 2140, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 13:
634 can be fit into 2380 3 times, resulting in a remainder of 478.
The next digit of our result is 3. 
Result so far: 101769.12933
Subtract 1902 from 2380 to get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

In conclusion, the division gives 101769.12933 with a balance of 0.000478.
