We divide 70403165 by 123
We want to figure out the number of times 70403165 can be divided by 123.

On to step 1:
The number 123 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 123

Advancing to step 2:
123 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Include the next digit (4) from the dividend after 70, then repeat: 704 / 123

Going ahead to step 3:
123 goes into 704 5 times with a remainder of 89.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 615 from 704, we get 89.
Fetch the next digit (0) from the dividend, attach it to 89 and continue: 890 / 123

On to step 4:
When dividing 890 by 123, we get 7 with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Deduct 861 from 890 and we're left with 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 123

Let's proceed to step 5:
When dividing 293 by 123, we get 2 with a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 572.0
If we take 246 away from 293, we end up with 47.
Fetch the next digit (1) from the dividend, attach it to 47 and continue: 471 / 123

Going ahead to step 6:
When dividing 471 by 123, we get 3 with a remainder of 102.
Use 3 as the next digit of our solution. 
Result so far: 5723.0
Deduct 369 from 471 and we're left with 102.
Grab the next digit (6) from the dividend, add it to 102, then carry on: 1026 / 123

On to step 7:
123 can be fit into 1026 8 times, resulting in a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 57238.0
Subtract 984 from 1026 to get 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 123

Let's proceed to step 8:
123 goes into 425 3 times with a remainder of 56.
Put 3 as the next digit of the answer. 
Result so far: 572383.0
Deduct 369 from 425 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
123 can be fit into 560 4 times, resulting in a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 572383.4
If we subtract 492 from 560, 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.

Let's proceed to step 10:
If we divide 680 by 123, we get 5 and a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 572383.45
Subtracting 615 from 680 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 11:
123 can be fit into 650 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 572383.455
Subtract 615 from 650 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 572383.455 with a remainder of 0.0035.
