We're dividing 77509539 by 627 
Let's see how many times 627 fits into 77509539.

Step 1:
627 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.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 627

Moving on to step 2:
When dividing 77 by 627, we get 0 with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 627

Step 3:
775 divided by 627 is 1 with a remainder of 148.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 627 from 775 to get 148.
Grab the next digit (0) from the dividend, add it to 148, then carry on: 1480 / 627

Moving on to step 4:
1480 divided by 627 is 2 with a remainder of 226.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 226 after subtracting 1254 from 1480.
Grab the next digit (9) from the dividend, add it to 226, then carry on: 2269 / 627

Moving on to step 5:
627 can be fit into 2269 3 times, resulting in a remainder of 388.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Deduct 1881 from 2269 and we're left with 388.
Include the next digit (5) from the dividend after 388, then repeat: 3885 / 627

On to step 6:
627 goes into 3885 6 times with a remainder of 123.
The number 6 becomes the next digit in our result. 
Result so far: 1236.0
Subtract 3762 from 3885 to get 123.
Take the next digit (3) from the dividend and append it to 123, then repeat: 1233 / 627

Let's proceed to step 7:
When dividing 1233 by 627, we get 1 with a remainder of 606.
The number 1 becomes the next digit in our result. 
Result so far: 12361.0
Subtract 627 from 1233 to get 606.
Append the next digit (9) from the dividend to 606 and continue with: 6069 / 627

Step 8:
If we divide 6069 by 627, we get 9 and a remainder of 426.
The number 9 becomes the next digit in our result. 
Result so far: 123619.0
If we take 5643 away from 6069, we end up with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Going ahead to step 9:
4260 divided by 627 is 6 with a remainder of 498.
Write down 6 as next digit of the result. 
Result so far: 123619.6
Subtracting 3762 from 4260 leaves us with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Going ahead to step 10:
627 can be fit into 4980 7 times, resulting in a remainder of 591.
Put 7 as the next digit of the answer. 
Result so far: 123619.67
The remainder is 591 after subtracting 4389 from 4980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Going ahead to step 11:
5910 divided by 627 is 9 with a remainder of 267.
Record the quotient 9 as the next digit in the result. 
Result so far: 123619.679
If we subtract 5643 from 5910, we get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 12:
If we divide 2670 by 627, we get 4 and a remainder of 162.
Put 4 as the next digit of the answer. 
Result so far: 123619.6794
If we subtract 2508 from 2670, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 13:
1620 divided by 627 is 2 with a remainder of 366.
Write down 2 as next digit of the result. 
Result so far: 123619.67942
Subtract 1254 from 1620 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 14:
The number 627 fits into 3660 5 times, leaving a remainder of 525.
Use 5 as the next digit of our solution. 
Result so far: 123619.679425
Deduct 3135 from 3660 and we're left with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Moving on to step 15:
627 can be fit into 5250 8 times, resulting in a remainder of 234.
Use 8 as the next digit of our solution. 
Result so far: 123619.6794258
Deduct 5016 from 5250 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 16:
627 can be fit into 2340 3 times, resulting in a remainder of 459.
Use 3 as the next digit of our solution. 
Result so far: 123619.67942583
If we take 1881 away from 2340, we end up with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

The final outcome is 123619.67942583, with a leftover of 4.59e-07.
