Let's divide 221637 by 77
We want to figure out the number of times 221637 can be divided by 77.

Advancing to step 1:
77 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 77

On to step 2:
When dividing 22 by 77, we get 0 with a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 22 after subtracting 0 from 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 77

Advancing to step 3:
77 can be fit into 221 2 times, resulting in a remainder of 67.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 154 from 221, we get 67.
Bring next digit (6) of the dividend behind the 67 and repeat the process: 676 / 77

Moving on to step 4:
If we divide 676 by 77, we get 8 and a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 60 after subtracting 616 from 676.
Bring next digit (3) of the dividend behind the 60 and repeat the process: 603 / 77

Let's proceed to step 5:
If we divide 603 by 77, we get 7 and a remainder of 64.
Put 7 as the next digit of the answer. 
Result so far: 287.0
The remainder is 64 after subtracting 539 from 603.
Append the next digit (7) from the dividend to 64 and continue with: 647 / 77

Advancing to step 6:
77 goes into 647 8 times with a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 2878.0
Deduct 616 from 647 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
When dividing 310 by 77, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 2878.4
The remainder is 2 after subtracting 308 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
When dividing 20 by 77, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 2878.4
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 77, we get 2 with a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 2878.402
Deduct 154 from 200 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 10:
460 divided by 77 is 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 2878.4025
Deduct 385 from 460 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 11:
77 can be fit into 750 9 times, resulting in a remainder of 57.
The next digit of our result is 9. 
Result so far: 2878.40259
Subtracting 693 from 750 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 12:
570 divided by 77 is 7 with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 2878.402597
Deduct 539 from 570 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 13:
When dividing 310 by 77, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 2878.4025974
If we subtract 308 from 310, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
20 divided by 77 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 2878.4025974
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 2878.4025974 with a remaining 2e-08.
