We divide 51501611 by 42
We want to divide 51501611 by 42.

Going ahead to step 1:
When dividing 5 by 42, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 42

Going ahead to step 2:
51 divided by 42 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 42 from 51 leaves us with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 42

Step 3:
If we divide 95 by 42, we get 2 and a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 84 away from 95, we end up with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 42

Going ahead to step 4:
110 divided by 42 is 2 with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
Subtract 84 from 110 to get 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 42

Step 5:
The number 42 fits into 261 6 times, leaving a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 1226.0
The remainder is 9 after subtracting 252 from 261.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 42

Going ahead to step 6:
If we divide 96 by 42, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 12262.0
If we subtract 84 from 96, we get 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 42

Advancing to step 7:
121 divided by 42 is 2 with a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 122622.0
Deduct 84 from 121 and we're left with 37.
Bring next digit (1) of the dividend behind the 37 and repeat the process: 371 / 42

On to step 8:
371 divided by 42 is 8 with a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 1226228.0
If we take 336 away from 371, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
42 goes into 350 8 times with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 1226228.8
Subtracting 336 from 350 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
42 can be fit into 140 3 times, resulting in a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 1226228.83
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
140 divided by 42 is 3 with a remainder of 14.
The next digit of our result is 3. 
Result so far: 1226228.833
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 1226228.833 with a balance of 0.0014.
