We look at the division of 84222571 by 139 
We're looking to find how many times 139 goes into 84222571.

On to step 1:
139 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 139

On to step 2:
139 goes into 84 0 times with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Take the next digit (2) from the dividend and append it to 84, then repeat: 842 / 139

On to step 3:
139 can be fit into 842 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 834 from 842 and we're left with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 139

Let's proceed to step 4:
82 divided by 139 is 0 with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 60.0
If we take 0 away from 82, we end up with 82.
Include the next digit (2) from the dividend after 82, then repeat: 822 / 139

Let's proceed to step 5:
139 can be fit into 822 5 times, resulting in a remainder of 127.
The next digit of our result is 5. 
Result so far: 605.0
If we subtract 695 from 822, we get 127.
Grab the next digit (5) from the dividend, add it to 127, then carry on: 1275 / 139

Going ahead to step 6:
The number 139 fits into 1275 9 times, leaving a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 6059.0
If we subtract 1251 from 1275, we get 24.
Take the next digit (7) from the dividend and append it to 24, then repeat: 247 / 139

Going ahead to step 7:
139 goes into 247 1 times with a remainder of 108.
Record the quotient 1 as the next digit in the result. 
Result so far: 60591.0
Deduct 139 from 247 and we're left with 108.
Take the next digit (1) from the dividend and append it to 108, then repeat: 1081 / 139

Going ahead to step 8:
When dividing 1081 by 139, we get 7 with a remainder of 108.
The number 7 becomes the next digit in our result. 
Result so far: 605917.0
Subtract 973 from 1081 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 9:
139 can be fit into 1080 7 times, resulting in a remainder of 107.
Put 7 as the next digit of the answer. 
Result so far: 605917.7
If we subtract 973 from 1080, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 10:
139 can be fit into 1070 7 times, resulting in a remainder of 97.
Put 7 as the next digit of the answer. 
Result so far: 605917.77
Deduct 973 from 1070 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

After the division, we end up with 605917.77 and a remainder of 0.097.
