We divide 49121961 by 639
Let's see how many times 639 fits into 49121961.

Moving on to step 1:
The number 639 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 639

On to step 2:
639 goes into 49 0 times with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 639

Going ahead to step 3:
The number 639 fits into 491 0 times, leaving a remainder of 491.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 491 and we're left with 491.
Take the next digit (2) from the dividend and append it to 491, then repeat: 4912 / 639

Going ahead to step 4:
4912 divided by 639 is 7 with a remainder of 439.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 4473 from 4912, we get 439.
Include the next digit (1) from the dividend after 439, then repeat: 4391 / 639

Moving on to step 5:
4391 divided by 639 is 6 with a remainder of 557.
Write down 6 as next digit of the result. 
Result so far: 76.0
Deduct 3834 from 4391 and we're left with 557.
Bring next digit (9) of the dividend behind the 557 and repeat the process: 5579 / 639

Advancing to step 6:
When dividing 5579 by 639, we get 8 with a remainder of 467.
Record the quotient 8 as the next digit in the result. 
Result so far: 768.0
If we subtract 5112 from 5579, we get 467.
Bring next digit (6) of the dividend behind the 467 and repeat the process: 4676 / 639

Step 7:
The number 639 fits into 4676 7 times, leaving a remainder of 203.
The next digit of our result is 7. 
Result so far: 7687.0
Subtract 4473 from 4676 to get 203.
Include the next digit (1) from the dividend after 203, then repeat: 2031 / 639

Moving on to step 8:
When dividing 2031 by 639, we get 3 with a remainder of 114.
Write down 3 as next digit of the result. 
Result so far: 76873.0
Subtract 1917 from 2031 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 9:
639 can be fit into 1140 1 times, resulting in a remainder of 501.
Put 1 as the next digit of the answer. 
Result so far: 76873.1
The remainder is 501 after subtracting 639 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Moving on to step 10:
When dividing 5010 by 639, we get 7 with a remainder of 537.
Record the quotient 7 as the next digit in the result. 
Result so far: 76873.17
If we take 4473 away from 5010, we end up with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Going ahead to step 11:
639 can be fit into 5370 8 times, resulting in a remainder of 258.
The number 8 becomes the next digit in our result. 
Result so far: 76873.178
Subtract 5112 from 5370 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 12:
If we divide 2580 by 639, we get 4 and a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 76873.1784
Subtract 2556 from 2580 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
639 goes into 240 0 times with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 76873.1784
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 14:
When dividing 2400 by 639, we get 3 with a remainder of 483.
Record the quotient 3 as the next digit in the result. 
Result so far: 76873.178403
Subtracting 1917 from 2400 leaves us with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Let's proceed to step 15:
4830 divided by 639 is 7 with a remainder of 357.
Put 7 as the next digit of the answer. 
Result so far: 76873.1784037
Deduct 4473 from 4830 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Step 16:
If we divide 3570 by 639, we get 5 and a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 76873.17840375
Subtracting 3195 from 3570 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

In conclusion, the division gives 76873.17840375 with a balance of 3.75e-07.
