7524470 ÷ 639 
We want to divide 7524470 by 639.

Step 1:
The number 639 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 639

Going ahead to step 2:
639 goes into 75 0 times with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Take the next digit (2) from the dividend and append it to 75, then repeat: 752 / 639

Let's proceed to step 3:
The number 639 fits into 752 1 times, leaving a remainder of 113.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 639 from 752 to get 113.
Fetch the next digit (4) from the dividend, attach it to 113 and continue: 1134 / 639

Let's proceed to step 4:
When dividing 1134 by 639, we get 1 with a remainder of 495.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 495 after subtracting 639 from 1134.
Take the next digit (4) from the dividend and append it to 495, then repeat: 4954 / 639

Step 5:
4954 divided by 639 is 7 with a remainder of 481.
Put 7 as the next digit of the answer. 
Result so far: 117.0
Subtracting 4473 from 4954 leaves us with 481.
Append the next digit (7) from the dividend to 481 and continue with: 4817 / 639

Advancing to step 6:
If we divide 4817 by 639, we get 7 and a remainder of 344.
Write down 7 as next digit of the result. 
Result so far: 1177.0
Subtract 4473 from 4817 to get 344.
Fetch the next digit (0) from the dividend, attach it to 344 and continue: 3440 / 639

Moving on to step 7:
If we divide 3440 by 639, we get 5 and a remainder of 245.
The number 5 becomes the next digit in our result. 
Result so far: 11775.0
The remainder is 245 after subtracting 3195 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 8:
The number 639 fits into 2450 3 times, leaving a remainder of 533.
Use 3 as the next digit of our solution. 
Result so far: 11775.3
Deduct 1917 from 2450 and we're left with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Moving on to step 9:
The number 639 fits into 5330 8 times, leaving a remainder of 218.
Use 8 as the next digit of our solution. 
Result so far: 11775.38
If we subtract 5112 from 5330, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 10:
639 can be fit into 2180 3 times, resulting in a remainder of 263.
Record the quotient 3 as the next digit in the result. 
Result so far: 11775.383
If we take 1917 away from 2180, we end up with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 11:
If we divide 2630 by 639, we get 4 and a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 11775.3834
Subtracting 2556 from 2630 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 12:
When dividing 740 by 639, we get 1 with a remainder of 101.
The number 1 becomes the next digit in our result. 
Result so far: 11775.38341
Subtract 639 from 740 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 13:
The number 639 fits into 1010 1 times, leaving a remainder of 371.
The next digit of our result is 1. 
Result so far: 11775.383411
Subtract 639 from 1010 to get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

The final outcome is 11775.383411, with a leftover of 3.71e-05.
