We're dividing 78072741 by 124 
Let's see how many times 124 fits into 78072741.

On to step 1:
If we divide 7 by 124, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 124

Going ahead to step 2:
The number 124 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 124

Advancing to step 3:
124 can be fit into 780 6 times, resulting in a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 744 from 780 to get 36.
Bring next digit (7) of the dividend behind the 36 and repeat the process: 367 / 124

Moving on to step 4:
When dividing 367 by 124, we get 2 with a remainder of 119.
Use 2 as the next digit of our solution. 
Result so far: 62.0
The remainder is 119 after subtracting 248 from 367.
Grab the next digit (2) from the dividend, add it to 119, then carry on: 1192 / 124

Step 5:
124 goes into 1192 9 times with a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 629.0
Subtract 1116 from 1192 to get 76.
Include the next digit (7) from the dividend after 76, then repeat: 767 / 124

Going ahead to step 6:
If we divide 767 by 124, we get 6 and a remainder of 23.
Use 6 as the next digit of our solution. 
Result so far: 6296.0
The remainder is 23 after subtracting 744 from 767.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 124

Moving on to step 7:
When dividing 234 by 124, we get 1 with a remainder of 110.
Put 1 as the next digit of the answer. 
Result so far: 62961.0
Subtracting 124 from 234 leaves us with 110.
Bring next digit (1) of the dividend behind the 110 and repeat the process: 1101 / 124

Moving on to step 8:
When dividing 1101 by 124, we get 8 with a remainder of 109.
The number 8 becomes the next digit in our result. 
Result so far: 629618.0
Subtract 992 from 1101 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 9:
124 can be fit into 1090 8 times, resulting in a remainder of 98.
Put 8 as the next digit of the answer. 
Result so far: 629618.8
Deduct 992 from 1090 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 10:
124 goes into 980 7 times with a remainder of 112.
Use 7 as the next digit of our solution. 
Result so far: 629618.87
Subtracting 868 from 980 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 11:
If we divide 1120 by 124, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 629618.879
Subtract 1116 from 1120 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
124 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 629618.879
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
If we divide 400 by 124, we get 3 and a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 629618.87903
Subtracting 372 from 400 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
If we divide 280 by 124, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 629618.879032
If we take 248 away from 280, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 15:
When dividing 320 by 124, we get 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 629618.8790322
Subtract 248 from 320 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 629618.8790322 with a remainder of 7.2e-07.
