We divide 73443100 by 639
We want to figure out the number of times 73443100 can be divided by 639.

Advancing to step 1:
When dividing 7 by 639, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 639

Advancing to step 2:
639 can be fit into 73 0 times, resulting in a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Grab the next digit (4) from the dividend, add it to 73, then carry on: 734 / 639

On to step 3:
The number 639 fits into 734 1 times, leaving a remainder of 95.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 639 from 734, we get 95.
Fetch the next digit (4) from the dividend, attach it to 95 and continue: 954 / 639

Going ahead to step 4:
The number 639 fits into 954 1 times, leaving a remainder of 315.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 315 after subtracting 639 from 954.
Fetch the next digit (3) from the dividend, attach it to 315 and continue: 3153 / 639

Advancing to step 5:
639 can be fit into 3153 4 times, resulting in a remainder of 597.
The next digit of our result is 4. 
Result so far: 114.0
Deduct 2556 from 3153 and we're left with 597.
Include the next digit (1) from the dividend after 597, then repeat: 5971 / 639

Let's proceed to step 6:
When dividing 5971 by 639, we get 9 with a remainder of 220.
Write down 9 as next digit of the result. 
Result so far: 1149.0
If we take 5751 away from 5971, we end up with 220.
Fetch the next digit (0) from the dividend, attach it to 220 and continue: 2200 / 639

Let's proceed to step 7:
2200 divided by 639 is 3 with a remainder of 283.
The next digit of our result is 3. 
Result so far: 11493.0
If we take 1917 away from 2200, we end up with 283.
Bring next digit (0) of the dividend behind the 283 and repeat the process: 2830 / 639

Step 8:
2830 divided by 639 is 4 with a remainder of 274.
Write down 4 as next digit of the result. 
Result so far: 114934.0
Deduct 2556 from 2830 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 9:
The number 639 fits into 2740 4 times, leaving a remainder of 184.
Record the quotient 4 as the next digit in the result. 
Result so far: 114934.4
If we take 2556 away from 2740, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 10:
If we divide 1840 by 639, we get 2 and a remainder of 562.
Use 2 as the next digit of our solution. 
Result so far: 114934.42
If we subtract 1278 from 1840, we get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Moving on to step 11:
5620 divided by 639 is 8 with a remainder of 508.
Record the quotient 8 as the next digit in the result. 
Result so far: 114934.428
Deduct 5112 from 5620 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 12:
639 can be fit into 5080 7 times, resulting in a remainder of 607.
Record the quotient 7 as the next digit in the result. 
Result so far: 114934.4287
Subtract 4473 from 5080 to get 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

On to step 13:
6070 divided by 639 is 9 with a remainder of 319.
Record the quotient 9 as the next digit in the result. 
Result so far: 114934.42879
Deduct 5751 from 6070 and we're left with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Going ahead to step 14:
639 goes into 3190 4 times with a remainder of 634.
The next digit of our result is 4. 
Result so far: 114934.428794
Subtracting 2556 from 3190 leaves us with 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Let's proceed to step 15:
When dividing 6340 by 639, we get 9 with a remainder of 589.
Put 9 as the next digit of the answer. 
Result so far: 114934.4287949
Deduct 5751 from 6340 and we're left with 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Step 16:
639 goes into 5890 9 times with a remainder of 139.
Record the quotient 9 as the next digit in the result. 
Result so far: 114934.42879499
The remainder is 139 after subtracting 5751 from 5890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Our division results in 114934.42879499 with a remaining 1.39e-07.
