51450232 ÷ 987 
We want to figure out the number of times 51450232 can be divided by 987.

Step 1:
987 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 987

Advancing to step 2:
987 can be fit into 51 0 times, resulting in a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 987

Going ahead to step 3:
If we divide 514 by 987, we get 0 and a remainder of 514.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 514 and we're left with 514.
Take the next digit (5) from the dividend and append it to 514, then repeat: 5145 / 987

On to step 4:
If we divide 5145 by 987, we get 5 and a remainder of 210.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 4935 from 5145 and we're left with 210.
Bring next digit (0) of the dividend behind the 210 and repeat the process: 2100 / 987

On to step 5:
When dividing 2100 by 987, we get 2 with a remainder of 126.
Write down 2 as next digit of the result. 
Result so far: 52.0
The remainder is 126 after subtracting 1974 from 2100.
Append the next digit (2) from the dividend to 126 and continue with: 1262 / 987

Step 6:
When dividing 1262 by 987, we get 1 with a remainder of 275.
Write down 1 as next digit of the result. 
Result so far: 521.0
Subtracting 987 from 1262 leaves us with 275.
Fetch the next digit (3) from the dividend, attach it to 275 and continue: 2753 / 987

On to step 7:
987 goes into 2753 2 times with a remainder of 779.
Use 2 as the next digit of our solution. 
Result so far: 5212.0
If we take 1974 away from 2753, we end up with 779.
Grab the next digit (2) from the dividend, add it to 779, then carry on: 7792 / 987

Step 8:
If we divide 7792 by 987, we get 7 and a remainder of 883.
Write down 7 as next digit of the result. 
Result so far: 52127.0
Subtracting 6909 from 7792 leaves us with 883.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8830, and continue the process.

Moving on to step 9:
987 goes into 8830 8 times with a remainder of 934.
Write down 8 as next digit of the result. 
Result so far: 52127.8
The remainder is 934 after subtracting 7896 from 8830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9340, and continue the process.

Advancing to step 10:
If we divide 9340 by 987, we get 9 and a remainder of 457.
The next digit of our result is 9. 
Result so far: 52127.89
If we subtract 8883 from 9340, we get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Going ahead to step 11:
When dividing 4570 by 987, we get 4 with a remainder of 622.
The next digit of our result is 4. 
Result so far: 52127.894
The remainder is 622 after subtracting 3948 from 4570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Step 12:
The number 987 fits into 6220 6 times, leaving a remainder of 298.
Record the quotient 6 as the next digit in the result. 
Result so far: 52127.8946
If we subtract 5922 from 6220, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Let's proceed to step 13:
2980 divided by 987 is 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 52127.89463
If we take 2961 away from 2980, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 14:
The number 987 fits into 190 0 times, leaving a remainder of 190.
Put 0 as the next digit of the answer. 
Result so far: 52127.89463
The remainder is 190 after subtracting 0 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 15:
987 goes into 1900 1 times with a remainder of 913.
Put 1 as the next digit of the answer. 
Result so far: 52127.8946301
If we take 987 away from 1900, we end up with 913.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9130, and continue the process.

Let's proceed to step 16:
If we divide 9130 by 987, we get 9 and a remainder of 247.
Record the quotient 9 as the next digit in the result. 
Result so far: 52127.89463019
Subtracting 8883 from 9130 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

In conclusion, the division gives 52127.89463019 with a balance of 2.47e-07.
