61170478 ÷ 639 
Our goal is to divide 61170478 by 639.

Moving on to step 1:
If we divide 6 by 639, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 639

Advancing to step 2:
When dividing 61 by 639, we get 0 with a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Bring next digit (1) of the dividend behind the 61 and repeat the process: 611 / 639

Advancing to step 3:
If we divide 611 by 639, we get 0 and a remainder of 611.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 611 leaves us with 611.
Bring next digit (7) of the dividend behind the 611 and repeat the process: 6117 / 639

Advancing to step 4:
When dividing 6117 by 639, we get 9 with a remainder of 366.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 5751 from 6117 to get 366.
Grab the next digit (0) from the dividend, add it to 366, then carry on: 3660 / 639

Step 5:
If we divide 3660 by 639, we get 5 and a remainder of 465.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
Deduct 3195 from 3660 and we're left with 465.
Bring next digit (4) of the dividend behind the 465 and repeat the process: 4654 / 639

Going ahead to step 6:
The number 639 fits into 4654 7 times, leaving a remainder of 181.
The next digit of our result is 7. 
Result so far: 957.0
Subtract 4473 from 4654 to get 181.
Append the next digit (7) from the dividend to 181 and continue with: 1817 / 639

On to step 7:
The number 639 fits into 1817 2 times, leaving a remainder of 539.
Write down 2 as next digit of the result. 
Result so far: 9572.0
If we take 1278 away from 1817, we end up with 539.
Fetch the next digit (8) from the dividend, attach it to 539 and continue: 5398 / 639

Let's proceed to step 8:
639 goes into 5398 8 times with a remainder of 286.
Put 8 as the next digit of the answer. 
Result so far: 95728.0
Subtracting 5112 from 5398 leaves us with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 9:
639 can be fit into 2860 4 times, resulting in a remainder of 304.
The number 4 becomes the next digit in our result. 
Result so far: 95728.4
If we subtract 2556 from 2860, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 10:
The number 639 fits into 3040 4 times, leaving a remainder of 484.
Put 4 as the next digit of the answer. 
Result so far: 95728.44
If we subtract 2556 from 3040, we get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

In conclusion, the division gives 95728.44 with a balance of 0.484.
