124721 divided by 45 
We want to divide 124721 by 45.

Going ahead to step 1:
The number 45 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 45

Step 2:
12 divided by 45 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 45

Advancing to step 3:
The number 45 fits into 124 2 times, leaving a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 90 away from 124, we end up with 34.
Bring next digit (7) of the dividend behind the 34 and repeat the process: 347 / 45

Going ahead to step 4:
347 divided by 45 is 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we take 315 away from 347, we end up with 32.
Include the next digit (2) from the dividend after 32, then repeat: 322 / 45

Going ahead to step 5:
45 can be fit into 322 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 277.0
Subtracting 315 from 322 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 45

Going ahead to step 6:
When dividing 71 by 45, we get 1 with a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 2771.0
The remainder is 26 after subtracting 45 from 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
The number 45 fits into 260 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 2771.5
Subtract 225 from 260 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.

Moving on to step 8:
45 goes into 350 7 times with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 2771.57
Deduct 315 from 350 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
45 can be fit into 350 7 times, resulting in a remainder of 35.
The next digit of our result is 7. 
Result so far: 2771.577
The remainder is 35 after subtracting 315 from 350.
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 2771.577 with a remainder of 0.0035.
