74460687 divided by 639 
Our goal is to divide 74460687 by 639.

On to step 1:
The number 639 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 639

Moving on to step 2:
When dividing 74 by 639, we get 0 with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Grab the next digit (4) from the dividend, add it to 74, then carry on: 744 / 639

Going ahead to step 3:
The number 639 fits into 744 1 times, leaving a remainder of 105.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 639 from 744 and we're left with 105.
Append the next digit (6) from the dividend to 105 and continue with: 1056 / 639

Going ahead to step 4:
639 goes into 1056 1 times with a remainder of 417.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 639 from 1056, we get 417.
Bring next digit (0) of the dividend behind the 417 and repeat the process: 4170 / 639

Moving on to step 5:
4170 divided by 639 is 6 with a remainder of 336.
Put 6 as the next digit of the answer. 
Result so far: 116.0
Subtract 3834 from 4170 to get 336.
Append the next digit (6) from the dividend to 336 and continue with: 3366 / 639

Let's proceed to step 6:
The number 639 fits into 3366 5 times, leaving a remainder of 171.
Record the quotient 5 as the next digit in the result. 
Result so far: 1165.0
The remainder is 171 after subtracting 3195 from 3366.
Include the next digit (8) from the dividend after 171, then repeat: 1718 / 639

Advancing to step 7:
1718 divided by 639 is 2 with a remainder of 440.
Record the quotient 2 as the next digit in the result. 
Result so far: 11652.0
The remainder is 440 after subtracting 1278 from 1718.
Grab the next digit (7) from the dividend, add it to 440, then carry on: 4407 / 639

Step 8:
If we divide 4407 by 639, we get 6 and a remainder of 573.
Use 6 as the next digit of our solution. 
Result so far: 116526.0
Subtract 3834 from 4407 to get 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Advancing to step 9:
639 goes into 5730 8 times with a remainder of 618.
Record the quotient 8 as the next digit in the result. 
Result so far: 116526.8
If we take 5112 away from 5730, we end up with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Step 10:
6180 divided by 639 is 9 with a remainder of 429.
Record the quotient 9 as the next digit in the result. 
Result so far: 116526.89
Subtract 5751 from 6180 to get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Let's proceed to step 11:
The number 639 fits into 4290 6 times, leaving a remainder of 456.
Write down 6 as next digit of the result. 
Result so far: 116526.896
If we subtract 3834 from 4290, we get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 12:
639 can be fit into 4560 7 times, resulting in a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 116526.8967
The remainder is 87 after subtracting 4473 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 13:
When dividing 870 by 639, we get 1 with a remainder of 231.
The number 1 becomes the next digit in our result. 
Result so far: 116526.89671
Subtracting 639 from 870 leaves us with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 14:
639 goes into 2310 3 times with a remainder of 393.
Write down 3 as next digit of the result. 
Result so far: 116526.896713
Subtracting 1917 from 2310 leaves us with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Advancing to step 15:
639 goes into 3930 6 times with a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 116526.8967136
Subtract 3834 from 3930 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 16:
639 can be fit into 960 1 times, resulting in a remainder of 321.
Write down 1 as next digit of the result. 
Result so far: 116526.89671361
Subtracting 639 from 960 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

In conclusion, the division gives 116526.89671361 with a balance of 3.21e-07.
