We look at the division of 74812618 by 639 
We want to divide 74812618 by 639.

Advancing to step 1:
639 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 639

Going ahead to step 2:
The number 639 fits into 74 0 times, leaving a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Fetch the next digit (8) from the dividend, attach it to 74 and continue: 748 / 639

Moving on to step 3:
The number 639 fits into 748 1 times, leaving a remainder of 109.
The next digit of our result is 1. 
Result so far: 1.0
If we take 639 away from 748, we end up with 109.
Grab the next digit (1) from the dividend, add it to 109, then carry on: 1091 / 639

Step 4:
The number 639 fits into 1091 1 times, leaving a remainder of 452.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 639 from 1091, we get 452.
Bring next digit (2) of the dividend behind the 452 and repeat the process: 4522 / 639

On to step 5:
When dividing 4522 by 639, we get 7 with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Subtracting 4473 from 4522 leaves us with 49.
Grab the next digit (6) from the dividend, add it to 49, then carry on: 496 / 639

Going ahead to step 6:
If we divide 496 by 639, we get 0 and a remainder of 496.
Put 0 as the next digit of the answer. 
Result so far: 1170.0
Subtracting 0 from 496 leaves us with 496.
Take the next digit (1) from the dividend and append it to 496, then repeat: 4961 / 639

Going ahead to step 7:
639 can be fit into 4961 7 times, resulting in a remainder of 488.
Put 7 as the next digit of the answer. 
Result so far: 11707.0
If we take 4473 away from 4961, we end up with 488.
Bring next digit (8) of the dividend behind the 488 and repeat the process: 4888 / 639

Let's proceed to step 8:
The number 639 fits into 4888 7 times, leaving a remainder of 415.
Write down 7 as next digit of the result. 
Result so far: 117077.0
If we take 4473 away from 4888, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 9:
639 goes into 4150 6 times with a remainder of 316.
Record the quotient 6 as the next digit in the result. 
Result so far: 117077.6
If we subtract 3834 from 4150, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 10:
The number 639 fits into 3160 4 times, leaving a remainder of 604.
Put 4 as the next digit of the answer. 
Result so far: 117077.64
The remainder is 604 after subtracting 2556 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Let's proceed to step 11:
639 can be fit into 6040 9 times, resulting in a remainder of 289.
Write down 9 as next digit of the result. 
Result so far: 117077.649
Deduct 5751 from 6040 and we're left with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 12:
639 goes into 2890 4 times with a remainder of 334.
Write down 4 as next digit of the result. 
Result so far: 117077.6494
The remainder is 334 after subtracting 2556 from 2890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 13:
639 can be fit into 3340 5 times, resulting in a remainder of 145.
The next digit of our result is 5. 
Result so far: 117077.64945
The remainder is 145 after subtracting 3195 from 3340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 14:
The number 639 fits into 1450 2 times, leaving a remainder of 172.
Write down 2 as next digit of the result. 
Result so far: 117077.649452
Subtracting 1278 from 1450 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 15:
1720 divided by 639 is 2 with a remainder of 442.
The next digit of our result is 2. 
Result so far: 117077.6494522
If we subtract 1278 from 1720, we get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

The final result is 117077.6494522 with a remainder of 4.42e-06.
