We look at the division of 77428219 by 122 
We want to figure out the number of times 77428219 can be divided by 122.

Going ahead to step 1:
122 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 122

Let's proceed to step 2:
77 divided by 122 is 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Take the next digit (4) from the dividend and append it to 77, then repeat: 774 / 122

Let's proceed to step 3:
If we divide 774 by 122, we get 6 and a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 42 after subtracting 732 from 774.
Fetch the next digit (2) from the dividend, attach it to 42 and continue: 422 / 122

Step 4:
422 divided by 122 is 3 with a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 63.0
Deduct 366 from 422 and we're left with 56.
Include the next digit (8) from the dividend after 56, then repeat: 568 / 122

Moving on to step 5:
If we divide 568 by 122, we get 4 and a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 634.0
The remainder is 80 after subtracting 488 from 568.
Take the next digit (2) from the dividend and append it to 80, then repeat: 802 / 122

Moving on to step 6:
The number 122 fits into 802 6 times, leaving a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 6346.0
If we subtract 732 from 802, we get 70.
Bring next digit (1) of the dividend behind the 70 and repeat the process: 701 / 122

Moving on to step 7:
If we divide 701 by 122, we get 5 and a remainder of 91.
Use 5 as the next digit of our solution. 
Result so far: 63465.0
The remainder is 91 after subtracting 610 from 701.
Bring next digit (9) of the dividend behind the 91 and repeat the process: 919 / 122

On to step 8:
The number 122 fits into 919 7 times, leaving a remainder of 65.
The number 7 becomes the next digit in our result. 
Result so far: 634657.0
If we take 854 away from 919, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 9:
122 goes into 650 5 times with a remainder of 40.
The next digit of our result is 5. 
Result so far: 634657.5
If we take 610 away from 650, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
When dividing 400 by 122, we get 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 634657.53
Subtract 366 from 400 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
The number 122 fits into 340 2 times, leaving a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 634657.532
Deduct 244 from 340 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 12:
122 can be fit into 960 7 times, resulting in a remainder of 106.
Write down 7 as next digit of the result. 
Result so far: 634657.5327
If we subtract 854 from 960, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 13:
1060 divided by 122 is 8 with a remainder of 84.
Put 8 as the next digit of the answer. 
Result so far: 634657.53278
Deduct 976 from 1060 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 14:
122 goes into 840 6 times with a remainder of 108.
Use 6 as the next digit of our solution. 
Result so far: 634657.532786
Subtracting 732 from 840 leaves us with 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 15:
1080 divided by 122 is 8 with a remainder of 104.
Use 8 as the next digit of our solution. 
Result so far: 634657.5327868
Subtracting 976 from 1080 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 16:
1040 divided by 122 is 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 634657.53278688
If we subtract 976 from 1040, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 634657.53278688, and the remainder is 6.4e-08.
