We divide 77800526 by 639
We're looking to find how many times 639 goes into 77800526.

On to step 1:
7 divided by 639 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 639

Moving on to step 2:
When dividing 77 by 639, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 639

Moving on to step 3:
639 can be fit into 778 1 times, resulting in a remainder of 139.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 639 from 778 and we're left with 139.
Include the next digit (0) from the dividend after 139, then repeat: 1390 / 639

Let's proceed to step 4:
639 can be fit into 1390 2 times, resulting in a remainder of 112.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 1278 from 1390, we get 112.
Take the next digit (0) from the dividend and append it to 112, then repeat: 1120 / 639

Let's proceed to step 5:
1120 divided by 639 is 1 with a remainder of 481.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
Deduct 639 from 1120 and we're left with 481.
Include the next digit (5) from the dividend after 481, then repeat: 4815 / 639

Let's proceed to step 6:
639 can be fit into 4815 7 times, resulting in a remainder of 342.
The number 7 becomes the next digit in our result. 
Result so far: 1217.0
Subtract 4473 from 4815 to get 342.
Append the next digit (2) from the dividend to 342 and continue with: 3422 / 639

Step 7:
If we divide 3422 by 639, we get 5 and a remainder of 227.
The next digit of our result is 5. 
Result so far: 12175.0
Deduct 3195 from 3422 and we're left with 227.
Grab the next digit (6) from the dividend, add it to 227, then carry on: 2276 / 639

Moving on to step 8:
2276 divided by 639 is 3 with a remainder of 359.
Put 3 as the next digit of the answer. 
Result so far: 121753.0
If we subtract 1917 from 2276, we get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

On to step 9:
639 goes into 3590 5 times with a remainder of 395.
Put 5 as the next digit of the answer. 
Result so far: 121753.5
If we take 3195 away from 3590, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 10:
639 can be fit into 3950 6 times, resulting in a remainder of 116.
Use 6 as the next digit of our solution. 
Result so far: 121753.56
Subtracting 3834 from 3950 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 11:
The number 639 fits into 1160 1 times, leaving a remainder of 521.
Put 1 as the next digit of the answer. 
Result so far: 121753.561
The remainder is 521 after subtracting 639 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

On to step 12:
When dividing 5210 by 639, we get 8 with a remainder of 98.
Use 8 as the next digit of our solution. 
Result so far: 121753.5618
If we subtract 5112 from 5210, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 13:
When dividing 980 by 639, we get 1 with a remainder of 341.
The number 1 becomes the next digit in our result. 
Result so far: 121753.56181
Subtracting 639 from 980 leaves us with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Advancing to step 14:
The number 639 fits into 3410 5 times, leaving a remainder of 215.
The next digit of our result is 5. 
Result so far: 121753.561815
Subtracting 3195 from 3410 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 15:
The number 639 fits into 2150 3 times, leaving a remainder of 233.
Write down 3 as next digit of the result. 
Result so far: 121753.5618153
If we subtract 1917 from 2150, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 16:
When dividing 2330 by 639, we get 3 with a remainder of 413.
Write down 3 as next digit of the result. 
Result so far: 121753.56181533
Subtract 1917 from 2330 to get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

The final result is 121753.56181533 with a remainder of 4.13e-07.
