If we subtract 0 from 7, we get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 639

On to step 2:
The number 639 fits into 74 0 times, leaving a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Fetch the next digit (8) from the dividend, attach it to 74 and continue: 748 / 639

Step 3:
The number 639 fits into 748 1 times, leaving a remainder of 109.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 639 from 748 to get 109.
Grab the next digit (6) from the dividend, add it to 109, then carry on: 1096 / 639

On to step 4:
1096 divided by 639 is 1 with a remainder of 457.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 639 away from 1096, we end up with 457.
Fetch the next digit (9) from the dividend, attach it to 457 and continue: 4579 / 639

Moving on to step 5:
If we divide 4579 by 639, we get 7 and a remainder of 106.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
If we take 4473 away from 4579, we end up with 106.
Bring next digit (3) of the dividend behind the 106 and repeat the process: 1063 / 639

Step 6:
If we divide 1063 by 639, we get 1 and a remainder of 424.
Put 1 as the next digit of the answer. 
Result so far: 1171.0
The remainder is 424 after subtracting 639 from 1063.
Append the next digit (1) from the dividend to 424 and continue with: 4241 / 639

On to step 7:
639 goes into 4241 6 times with a remainder of 407.
Record the quotient 6 as the next digit in the result. 
Result so far: 11716.0
Subtract 3834 from 4241 to get 407.
Grab the next digit (8) from the dividend, add it to 407, then carry on: 4078 / 639

Advancing to step 8:
4078 divided by 639 is 6 with a remainder of 244.
Use 6 as the next digit of our solution. 
Result so far: 117166.0
The remainder is 244 after subtracting 3834 from 4078.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 9:
639 can be fit into 2440 3 times, resulting in a remainder of 523.
The next digit of our result is 3. 
Result so far: 117166.3
Subtracting 1917 from 2440 leaves us with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Going ahead to step 10:
5230 divided by 639 is 8 with a remainder of 118.
Put 8 as the next digit of the answer. 
Result so far: 117166.38
Deduct 5112 from 5230 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 11:
The number 639 fits into 1180 1 times, leaving a remainder of 541.
Use 1 as the next digit of our solution. 
Result so far: 117166.381
Deduct 639 from 1180 and we're left with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Step 12:
If we divide 5410 by 639, we get 8 and a remainder of 298.
Use 8 as the next digit of our solution. 
Result so far: 117166.3818
If we take 5112 away from 5410, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 13:
The number 639 fits into 2980 4 times, leaving a remainder of 424.
Put 4 as the next digit of the answer. 
Result so far: 117166.38184
Subtract 2556 from 2980 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Advancing to step 14:
639 can be fit into 4240 6 times, resulting in a remainder of 406.
Put 6 as the next digit of the answer. 
Result so far: 117166.381846
The remainder is 406 after subtracting 3834 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 15:
639 can be fit into 4060 6 times, resulting in a remainder of 226.
Record the quotient 6 as the next digit in the result. 
Result so far: 117166.3818466
If we take 3834 away from 4060, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

After the division, we end up with 117166.3818466 and a remainder of 2.26e-06.
