We look at the division of 77386880 by 22 
We're looking to find how many times 22 goes into 77386880.

Let's proceed to step 1:
22 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
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 / 22

Let's proceed to step 2:
22 can be fit into 77 3 times, resulting in a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 66 from 77 and we're left with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 22

On to step 3:
22 goes into 113 5 times with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
The remainder is 3 after subtracting 110 from 113.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 22

Let's proceed to step 4:
The number 22 fits into 38 1 times, leaving a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 351.0
If we subtract 22 from 38, we get 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 22

Going ahead to step 5:
166 divided by 22 is 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 3517.0
The remainder is 12 after subtracting 154 from 166.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 22

Step 6:
22 goes into 128 5 times with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 35175.0
Deduct 110 from 128 and we're left with 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 22

Going ahead to step 7:
22 goes into 188 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 351758.0
Subtract 176 from 188 to get 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 22

On to step 8:
The number 22 fits into 120 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3517585.0
If we take 110 away from 120, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
The number 22 fits into 100 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 3517585.4
The remainder is 12 after subtracting 88 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
When dividing 120 by 22, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3517585.45
The remainder is 10 after subtracting 110 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
22 goes into 100 4 times with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 3517585.454
If we take 88 away from 100, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
When dividing 120 by 22, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3517585.4545
If we take 110 away from 120, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
When dividing 100 by 22, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 3517585.45454
The remainder is 12 after subtracting 88 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
When dividing 120 by 22, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3517585.454545
The remainder is 10 after subtracting 110 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 15:
100 divided by 22 is 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 3517585.4545454
The remainder is 12 after subtracting 88 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 16:
If we divide 120 by 22, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 3517585.45454545
If we subtract 110 from 120, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 3517585.45454545, with a leftover of 1e-08.
