We look at the division of 70423140 by 123 
We're looking to find how many times 123 goes into 70423140.

Let's proceed to step 1:
When dividing 7 by 123, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 123

Moving on to step 2:
If we divide 70 by 123, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Append the next digit (4) from the dividend to 70 and continue with: 704 / 123

Step 3:
123 can be fit into 704 5 times, resulting in a remainder of 89.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 615 from 704, we get 89.
Bring next digit (2) of the dividend behind the 89 and repeat the process: 892 / 123

Going ahead to step 4:
123 can be fit into 892 7 times, resulting in a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
If we subtract 861 from 892, we get 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 123

Going ahead to step 5:
When dividing 313 by 123, we get 2 with a remainder of 67.
Use 2 as the next digit of our solution. 
Result so far: 572.0
Subtract 246 from 313 to get 67.
Grab the next digit (1) from the dividend, add it to 67, then carry on: 671 / 123

On to step 6:
The number 123 fits into 671 5 times, leaving a remainder of 56.
The next digit of our result is 5. 
Result so far: 5725.0
Subtracting 615 from 671 leaves us with 56.
Bring next digit (4) of the dividend behind the 56 and repeat the process: 564 / 123

Going ahead to step 7:
123 can be fit into 564 4 times, resulting in a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 57254.0
If we subtract 492 from 564, we get 72.
Fetch the next digit (0) from the dividend, attach it to 72 and continue: 720 / 123

Let's proceed to step 8:
123 can be fit into 720 5 times, resulting in a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 572545.0
The remainder is 105 after subtracting 615 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 9:
When dividing 1050 by 123, we get 8 with a remainder of 66.
The next digit of our result is 8. 
Result so far: 572545.8
Deduct 984 from 1050 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
660 divided by 123 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 572545.85
Subtract 615 from 660 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 11:
123 goes into 450 3 times with a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 572545.853
If we subtract 369 from 450, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 12:
810 divided by 123 is 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 572545.8536
If we take 738 away from 810, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 13:
123 can be fit into 720 5 times, resulting in a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 572545.85365
If we subtract 615 from 720, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 14:
When dividing 1050 by 123, we get 8 with a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 572545.853658
The remainder is 66 after subtracting 984 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 15:
The number 123 fits into 660 5 times, leaving a remainder of 45.
The next digit of our result is 5. 
Result so far: 572545.8536585
Deduct 615 from 660 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 16:
123 can be fit into 450 3 times, resulting in a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 572545.85365853
If we take 369 away from 450, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

The final outcome is 572545.85365853, with a leftover of 8.1e-08.
