70586307 ÷ 123 
Let's see how many times 123 fits into 70586307.

Step 1:
123 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 123

Step 2:
123 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Include the next digit (5) from the dividend after 70, then repeat: 705 / 123

Advancing to step 3:
705 divided by 123 is 5 with a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 615 from 705 to get 90.
Take the next digit (8) from the dividend and append it to 90, then repeat: 908 / 123

Moving on to step 4:
123 can be fit into 908 7 times, resulting in a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtract 861 from 908 to get 47.
Include the next digit (6) from the dividend after 47, then repeat: 476 / 123

Going ahead to step 5:
The number 123 fits into 476 3 times, leaving a remainder of 107.
Record the quotient 3 as the next digit in the result. 
Result so far: 573.0
Subtracting 369 from 476 leaves us with 107.
Include the next digit (3) from the dividend after 107, then repeat: 1073 / 123

Let's proceed to step 6:
1073 divided by 123 is 8 with a remainder of 89.
Use 8 as the next digit of our solution. 
Result so far: 5738.0
The remainder is 89 after subtracting 984 from 1073.
Fetch the next digit (0) from the dividend, attach it to 89 and continue: 890 / 123

Step 7:
When dividing 890 by 123, we get 7 with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 57387.0
The remainder is 29 after subtracting 861 from 890.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 123

Advancing to step 8:
297 divided by 123 is 2 with a remainder of 51.
Write down 2 as next digit of the result. 
Result so far: 573872.0
Subtracting 246 from 297 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 9:
510 divided by 123 is 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 573872.4
If we take 492 away from 510, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
If we divide 180 by 123, we get 1 and a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 573872.41
If we subtract 123 from 180, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 11:
570 divided by 123 is 4 with a remainder of 78.
The next digit of our result is 4. 
Result so far: 573872.414
If we subtract 492 from 570, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 12:
When dividing 780 by 123, we get 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 573872.4146
The remainder is 42 after subtracting 738 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 13:
If we divide 420 by 123, we get 3 and a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 573872.41463
If we subtract 369 from 420, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 14:
If we divide 510 by 123, we get 4 and a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 573872.414634
The remainder is 18 after subtracting 492 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 15:
123 can be fit into 180 1 times, resulting in a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 573872.4146341
If we take 123 away from 180, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 16:
570 divided by 123 is 4 with a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 573872.41463414
Subtract 492 from 570 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final outcome is 573872.41463414, with a leftover of 7.8e-08.
