We're dividing 80563045 by 139 
We want to figure out the number of times 80563045 can be divided by 139.

Moving on to step 1:
If we divide 8 by 139, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 139

On to step 2:
139 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Grab the next digit (5) from the dividend, add it to 80, then carry on: 805 / 139

Going ahead to step 3:
805 divided by 139 is 5 with a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 695 away from 805, we end up with 110.
Grab the next digit (6) from the dividend, add it to 110, then carry on: 1106 / 139

Moving on to step 4:
If we divide 1106 by 139, we get 7 and a remainder of 133.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
If we take 973 away from 1106, we end up with 133.
Include the next digit (3) from the dividend after 133, then repeat: 1333 / 139

Going ahead to step 5:
If we divide 1333 by 139, we get 9 and a remainder of 82.
Record the quotient 9 as the next digit in the result. 
Result so far: 579.0
If we subtract 1251 from 1333, we get 82.
Include the next digit (0) from the dividend after 82, then repeat: 820 / 139

Moving on to step 6:
139 can be fit into 820 5 times, resulting in a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 5795.0
If we subtract 695 from 820, we get 125.
Grab the next digit (4) from the dividend, add it to 125, then carry on: 1254 / 139

Let's proceed to step 7:
139 can be fit into 1254 9 times, resulting in a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 57959.0
If we subtract 1251 from 1254, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 139

On to step 8:
The number 139 fits into 35 0 times, leaving a remainder of 35.
The next digit of our result is 0. 
Result so far: 579590.0
The remainder is 35 after subtracting 0 from 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
The number 139 fits into 350 2 times, leaving a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 579590.2
If we take 278 away from 350, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
If we divide 720 by 139, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 579590.25
Deduct 695 from 720 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
139 can be fit into 250 1 times, resulting in a remainder of 111.
Use 1 as the next digit of our solution. 
Result so far: 579590.251
Subtracting 139 from 250 leaves us with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 12:
139 can be fit into 1110 7 times, resulting in a remainder of 137.
Use 7 as the next digit of our solution. 
Result so far: 579590.2517
Subtract 973 from 1110 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Advancing to step 13:
If we divide 1370 by 139, we get 9 and a remainder of 119.
The next digit of our result is 9. 
Result so far: 579590.25179
Subtract 1251 from 1370 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

On to step 14:
When dividing 1190 by 139, we get 8 with a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 579590.251798
The remainder is 78 after subtracting 1112 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 15:
780 divided by 139 is 5 with a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 579590.2517985
Deduct 695 from 780 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 16:
850 divided by 139 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 579590.25179856
Subtract 834 from 850 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 579590.25179856 with a balance of 1.6e-08.
