We're dividing 61154508 by 639 
We're looking to find how many times 639 goes into 61154508.

On to step 1:
The number 639 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 639

Let's proceed to step 2:
61 divided by 639 is 0 with a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Include the next digit (1) from the dividend after 61, then repeat: 611 / 639

Moving on to step 3:
If we divide 611 by 639, we get 0 and a remainder of 611.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 611 and we're left with 611.
Include the next digit (5) from the dividend after 611, then repeat: 6115 / 639

Step 4:
6115 divided by 639 is 9 with a remainder of 364.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 5751 from 6115 to get 364.
Bring next digit (4) of the dividend behind the 364 and repeat the process: 3644 / 639

Advancing to step 5:
When dividing 3644 by 639, we get 5 with a remainder of 449.
Write down 5 as next digit of the result. 
Result so far: 95.0
If we subtract 3195 from 3644, we get 449.
Fetch the next digit (5) from the dividend, attach it to 449 and continue: 4495 / 639

Let's proceed to step 6:
4495 divided by 639 is 7 with a remainder of 22.
The next digit of our result is 7. 
Result so far: 957.0
Deduct 4473 from 4495 and we're left with 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 639

Step 7:
639 goes into 220 0 times with a remainder of 220.
The next digit of our result is 0. 
Result so far: 9570.0
The remainder is 220 after subtracting 0 from 220.
Bring next digit (8) of the dividend behind the 220 and repeat the process: 2208 / 639

Going ahead to step 8:
The number 639 fits into 2208 3 times, leaving a remainder of 291.
The number 3 becomes the next digit in our result. 
Result so far: 95703.0
Subtract 1917 from 2208 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Going ahead to step 9:
639 goes into 2910 4 times with a remainder of 354.
The number 4 becomes the next digit in our result. 
Result so far: 95703.4
Deduct 2556 from 2910 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 10:
639 can be fit into 3540 5 times, resulting in a remainder of 345.
The number 5 becomes the next digit in our result. 
Result so far: 95703.45
Deduct 3195 from 3540 and we're left with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Let's proceed to step 11:
639 goes into 3450 5 times with a remainder of 255.
Use 5 as the next digit of our solution. 
Result so far: 95703.455
If we subtract 3195 from 3450, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

After the division, we end up with 95703.455 and a remainder of 0.0255.
