199640 divided by 77 
We want to figure out the number of times 199640 can be divided by 77.

Let's proceed to step 1:
When dividing 1 by 77, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 77

Let's proceed to step 2:
If we divide 19 by 77, we get 0 and a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 77

Step 3:
199 divided by 77 is 2 with a remainder of 45.
The next digit of our result is 2. 
Result so far: 2.0
If we take 154 away from 199, we end up with 45.
Include the next digit (6) from the dividend after 45, then repeat: 456 / 77

Moving on to step 4:
456 divided by 77 is 5 with a remainder of 71.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we take 385 away from 456, we end up with 71.
Append the next digit (4) from the dividend to 71 and continue with: 714 / 77

On to step 5:
When dividing 714 by 77, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 259.0
Deduct 693 from 714 and we're left with 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 77

Moving on to step 6:
77 goes into 210 2 times with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 2592.0
If we subtract 154 from 210, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 7:
77 goes into 560 7 times with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 2592.7
Subtracting 539 from 560 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
77 can be fit into 210 2 times, resulting in a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 2592.72
Subtract 154 from 210 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
560 divided by 77 is 7 with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 2592.727
If we subtract 539 from 560, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
77 goes into 210 2 times with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 2592.7272
Subtracting 154 from 210 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
560 divided by 77 is 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 2592.72727
Subtracting 539 from 560 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 12:
If we divide 210 by 77, we get 2 and a remainder of 56.
The next digit of our result is 2. 
Result so far: 2592.727272
Deduct 154 from 210 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
If we divide 560 by 77, we get 7 and a remainder of 21.
The next digit of our result is 7. 
Result so far: 2592.7272727
If we subtract 539 from 560, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 14:
77 goes into 210 2 times with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 2592.72727272
Subtract 154 from 210 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.
