65051901 ÷ 123 
Our goal is to divide 65051901 by 123.

Advancing to step 1:
When dividing 6 by 123, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 123

Step 2:
The number 123 fits into 65 0 times, leaving a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Take the next digit (0) from the dividend and append it to 65, then repeat: 650 / 123

On to step 3:
If we divide 650 by 123, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 615 from 650 and we're left with 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 123

Let's proceed to step 4:
355 divided by 123 is 2 with a remainder of 109.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Subtracting 246 from 355 leaves us with 109.
Bring next digit (1) of the dividend behind the 109 and repeat the process: 1091 / 123

On to step 5:
1091 divided by 123 is 8 with a remainder of 107.
Record the quotient 8 as the next digit in the result. 
Result so far: 528.0
The remainder is 107 after subtracting 984 from 1091.
Include the next digit (9) from the dividend after 107, then repeat: 1079 / 123

Going ahead to step 6:
If we divide 1079 by 123, we get 8 and a remainder of 95.
Put 8 as the next digit of the answer. 
Result so far: 5288.0
The remainder is 95 after subtracting 984 from 1079.
Take the next digit (0) from the dividend and append it to 95, then repeat: 950 / 123

On to step 7:
If we divide 950 by 123, we get 7 and a remainder of 89.
Use 7 as the next digit of our solution. 
Result so far: 52887.0
If we take 861 away from 950, we end up with 89.
Fetch the next digit (1) from the dividend, attach it to 89 and continue: 891 / 123

Step 8:
When dividing 891 by 123, we get 7 with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 528877.0
If we take 861 away from 891, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
123 can be fit into 300 2 times, resulting in a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 528877.2
Subtract 246 from 300 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
123 goes into 540 4 times with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 528877.24
If we take 492 away from 540, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
The number 123 fits into 480 3 times, leaving a remainder of 111.
Record the quotient 3 as the next digit in the result. 
Result so far: 528877.243
Deduct 369 from 480 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 12:
When dividing 1110 by 123, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 528877.2439
Subtracting 1107 from 1110 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 13:
The number 123 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 528877.2439
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
If we divide 300 by 123, we get 2 and a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 528877.243902
If we take 246 away from 300, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 15:
123 goes into 540 4 times with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 528877.2439024
The remainder is 48 after subtracting 492 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 16:
If we divide 480 by 123, we get 3 and a remainder of 111.
Use 3 as the next digit of our solution. 
Result so far: 528877.24390243
If we subtract 369 from 480, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

The final result is 528877.24390243 with a remainder of 1.11e-07.
