77709054 ÷ 393 
We want to figure out the number of times 77709054 can be divided by 393.

Let's proceed to step 1:
When dividing 7 by 393, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 393

Step 2:
When dividing 77 by 393, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 393

On to step 3:
If we divide 777 by 393, we get 1 and a remainder of 384.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 384 after subtracting 393 from 777.
Fetch the next digit (0) from the dividend, attach it to 384 and continue: 3840 / 393

Advancing to step 4:
393 can be fit into 3840 9 times, resulting in a remainder of 303.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 3537 from 3840 and we're left with 303.
Append the next digit (9) from the dividend to 303 and continue with: 3039 / 393

Step 5:
393 can be fit into 3039 7 times, resulting in a remainder of 288.
Use 7 as the next digit of our solution. 
Result so far: 197.0
If we take 2751 away from 3039, we end up with 288.
Grab the next digit (0) from the dividend, add it to 288, then carry on: 2880 / 393

Moving on to step 6:
When dividing 2880 by 393, we get 7 with a remainder of 129.
The next digit of our result is 7. 
Result so far: 1977.0
Deduct 2751 from 2880 and we're left with 129.
Fetch the next digit (5) from the dividend, attach it to 129 and continue: 1295 / 393

Advancing to step 7:
393 can be fit into 1295 3 times, resulting in a remainder of 116.
The number 3 becomes the next digit in our result. 
Result so far: 19773.0
Subtract 1179 from 1295 to get 116.
Include the next digit (4) from the dividend after 116, then repeat: 1164 / 393

Let's proceed to step 8:
1164 divided by 393 is 2 with a remainder of 378.
Write down 2 as next digit of the result. 
Result so far: 197732.0
Subtract 786 from 1164 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Moving on to step 9:
393 can be fit into 3780 9 times, resulting in a remainder of 243.
Write down 9 as next digit of the result. 
Result so far: 197732.9
The remainder is 243 after subtracting 3537 from 3780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Advancing to step 10:
393 can be fit into 2430 6 times, resulting in a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 197732.96
Subtracting 2358 from 2430 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 11:
720 divided by 393 is 1 with a remainder of 327.
The number 1 becomes the next digit in our result. 
Result so far: 197732.961
The remainder is 327 after subtracting 393 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Going ahead to step 12:
393 can be fit into 3270 8 times, resulting in a remainder of 126.
Write down 8 as next digit of the result. 
Result so far: 197732.9618
Subtract 3144 from 3270 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 13:
1260 divided by 393 is 3 with a remainder of 81.
Write down 3 as next digit of the result. 
Result so far: 197732.96183
Deduct 1179 from 1260 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 14:
If we divide 810 by 393, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 197732.961832
Subtract 786 from 810 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 15:
If we divide 240 by 393, we get 0 and a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 197732.961832
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 16:
2400 divided by 393 is 6 with a remainder of 42.
The next digit of our result is 6. 
Result so far: 197732.96183206
Subtract 2358 from 2400 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 197732.96183206 with a remaining 4.2e-08.
