Let's divide 84454450 by 651
Let's see how many times 651 fits into 84454450.

Going ahead to step 1:
The number 651 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 651

Going ahead to step 2:
The number 651 fits into 84 0 times, leaving a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Append the next digit (4) from the dividend to 84 and continue with: 844 / 651

Let's proceed to step 3:
The number 651 fits into 844 1 times, leaving a remainder of 193.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 193 after subtracting 651 from 844.
Bring next digit (5) of the dividend behind the 193 and repeat the process: 1935 / 651

Moving on to step 4:
If we divide 1935 by 651, we get 2 and a remainder of 633.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 1302 from 1935 to get 633.
Take the next digit (4) from the dividend and append it to 633, then repeat: 6334 / 651

Moving on to step 5:
651 can be fit into 6334 9 times, resulting in a remainder of 475.
Put 9 as the next digit of the answer. 
Result so far: 129.0
If we subtract 5859 from 6334, we get 475.
Include the next digit (4) from the dividend after 475, then repeat: 4754 / 651

Moving on to step 6:
If we divide 4754 by 651, we get 7 and a remainder of 197.
The next digit of our result is 7. 
Result so far: 1297.0
Deduct 4557 from 4754 and we're left with 197.
Fetch the next digit (5) from the dividend, attach it to 197 and continue: 1975 / 651

Moving on to step 7:
651 goes into 1975 3 times with a remainder of 22.
The next digit of our result is 3. 
Result so far: 12973.0
Subtracting 1953 from 1975 leaves us with 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 651

Step 8:
If we divide 220 by 651, we get 0 and a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 129730.0
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 9:
The number 651 fits into 2200 3 times, leaving a remainder of 247.
The next digit of our result is 3. 
Result so far: 129730.3
Subtract 1953 from 2200 to get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 10:
If we divide 2470 by 651, we get 3 and a remainder of 517.
Put 3 as the next digit of the answer. 
Result so far: 129730.33
If we subtract 1953 from 2470, we get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

The final result is 129730.33 with a remainder of 0.517.
