Let's divide 51389405 by 111
Let's see how many times 111 fits into 51389405.

Moving on to step 1:
The number 111 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 111

Advancing to step 2:
51 divided by 111 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 111

On to step 3:
111 can be fit into 513 4 times, resulting in a remainder of 69.
The next digit of our result is 4. 
Result so far: 4.0
If we take 444 away from 513, we end up with 69.
Grab the next digit (8) from the dividend, add it to 69, then carry on: 698 / 111

Moving on to step 4:
698 divided by 111 is 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 46.0
Subtract 666 from 698 to get 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 111

Advancing to step 5:
If we divide 329 by 111, we get 2 and a remainder of 107.
Record the quotient 2 as the next digit in the result. 
Result so far: 462.0
Deduct 222 from 329 and we're left with 107.
Include the next digit (4) from the dividend after 107, then repeat: 1074 / 111

Going ahead to step 6:
111 can be fit into 1074 9 times, resulting in a remainder of 75.
The next digit of our result is 9. 
Result so far: 4629.0
Deduct 999 from 1074 and we're left with 75.
Bring next digit (0) of the dividend behind the 75 and repeat the process: 750 / 111

Step 7:
When dividing 750 by 111, we get 6 with a remainder of 84.
The next digit of our result is 6. 
Result so far: 46296.0
If we take 666 away from 750, we end up with 84.
Append the next digit (5) from the dividend to 84 and continue with: 845 / 111

Advancing to step 8:
When dividing 845 by 111, we get 7 with a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 462967.0
Subtract 777 from 845 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 9:
680 divided by 111 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 462967.6
Deduct 666 from 680 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.

Let's proceed to step 10:
111 goes into 140 1 times with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 462967.61
The remainder is 29 after subtracting 111 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 11:
111 goes into 290 2 times with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 462967.612
If we subtract 222 from 290, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 12:
The number 111 fits into 680 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 462967.6126
Subtract 666 from 680 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
111 goes into 140 1 times with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 462967.61261
Subtracting 111 from 140 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 14:
290 divided by 111 is 2 with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 462967.612612
If we subtract 222 from 290, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 15:
680 divided by 111 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 462967.6126126
If we subtract 666 from 680, we get 14.
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 16:
When dividing 140 by 111, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 462967.61261261
Subtract 111 from 140 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

In conclusion, the division gives 462967.61261261 with a balance of 2.9e-08.
