We look at the division of 45766168 by 639 
We're looking to find how many times 639 goes into 45766168.

Going ahead to step 1:
When dividing 4 by 639, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 639

Let's proceed to step 2:
When dividing 45 by 639, we get 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 639

On to step 3:
457 divided by 639 is 0 with a remainder of 457.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 457 leaves us with 457.
Include the next digit (6) from the dividend after 457, then repeat: 4576 / 639

Moving on to step 4:
If we divide 4576 by 639, we get 7 and a remainder of 103.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 4473 from 4576, we get 103.
Append the next digit (6) from the dividend to 103 and continue with: 1036 / 639

Step 5:
639 goes into 1036 1 times with a remainder of 397.
Write down 1 as next digit of the result. 
Result so far: 71.0
If we take 639 away from 1036, we end up with 397.
Include the next digit (1) from the dividend after 397, then repeat: 3971 / 639

Step 6:
639 can be fit into 3971 6 times, resulting in a remainder of 137.
Use 6 as the next digit of our solution. 
Result so far: 716.0
Subtract 3834 from 3971 to get 137.
Fetch the next digit (6) from the dividend, attach it to 137 and continue: 1376 / 639

Let's proceed to step 7:
1376 divided by 639 is 2 with a remainder of 98.
Use 2 as the next digit of our solution. 
Result so far: 7162.0
Subtracting 1278 from 1376 leaves us with 98.
Grab the next digit (8) from the dividend, add it to 98, then carry on: 988 / 639

Step 8:
The number 639 fits into 988 1 times, leaving a remainder of 349.
Record the quotient 1 as the next digit in the result. 
Result so far: 71621.0
If we take 639 away from 988, we end up with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Let's proceed to step 9:
When dividing 3490 by 639, we get 5 with a remainder of 295.
The number 5 becomes the next digit in our result. 
Result so far: 71621.5
If we take 3195 away from 3490, we end up with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Moving on to step 10:
When dividing 2950 by 639, we get 4 with a remainder of 394.
Write down 4 as next digit of the result. 
Result so far: 71621.54
The remainder is 394 after subtracting 2556 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 11:
When dividing 3940 by 639, we get 6 with a remainder of 106.
Write down 6 as next digit of the result. 
Result so far: 71621.546
Subtracting 3834 from 3940 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 12:
When dividing 1060 by 639, we get 1 with a remainder of 421.
The number 1 becomes the next digit in our result. 
Result so far: 71621.5461
Deduct 639 from 1060 and we're left with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Step 13:
If we divide 4210 by 639, we get 6 and a remainder of 376.
Record the quotient 6 as the next digit in the result. 
Result so far: 71621.54616
Subtract 3834 from 4210 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 14:
The number 639 fits into 3760 5 times, leaving a remainder of 565.
Use 5 as the next digit of our solution. 
Result so far: 71621.546165
The remainder is 565 after subtracting 3195 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Step 15:
The number 639 fits into 5650 8 times, leaving a remainder of 538.
Put 8 as the next digit of the answer. 
Result so far: 71621.5461658
Subtract 5112 from 5650 to get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Let's proceed to step 16:
639 goes into 5380 8 times with a remainder of 268.
The next digit of our result is 8. 
Result so far: 71621.54616588
The remainder is 268 after subtracting 5112 from 5380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The quotient of the division is 71621.54616588, and the remainder is 2.68e-07.
