We divide 77488406 by 393
We want to figure out the number of times 77488406 can be divided by 393.

Let's proceed to step 1:
The number 393 fits into 7 0 times, leaving 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.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 393

Moving on to step 2:
393 can be fit into 77 0 times, resulting in a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Append the next digit (4) from the dividend to 77 and continue with: 774 / 393

Let's proceed to step 3:
The number 393 fits into 774 1 times, leaving a remainder of 381.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 393 from 774, we get 381.
Grab the next digit (8) from the dividend, add it to 381, then carry on: 3818 / 393

Let's proceed to step 4:
If we divide 3818 by 393, we get 9 and a remainder of 281.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 3537 from 3818 to get 281.
Fetch the next digit (8) from the dividend, attach it to 281 and continue: 2818 / 393

Step 5:
393 goes into 2818 7 times with a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 197.0
Subtract 2751 from 2818 to get 67.
Grab the next digit (4) from the dividend, add it to 67, then carry on: 674 / 393

Advancing to step 6:
When dividing 674 by 393, we get 1 with a remainder of 281.
Record the quotient 1 as the next digit in the result. 
Result so far: 1971.0
If we take 393 away from 674, we end up with 281.
Grab the next digit (0) from the dividend, add it to 281, then carry on: 2810 / 393

Moving on to step 7:
393 can be fit into 2810 7 times, resulting in a remainder of 59.
The next digit of our result is 7. 
Result so far: 19717.0
Subtracting 2751 from 2810 leaves us with 59.
Take the next digit (6) from the dividend and append it to 59, then repeat: 596 / 393

Moving on to step 8:
393 goes into 596 1 times with a remainder of 203.
The number 1 becomes the next digit in our result. 
Result so far: 197171.0
Subtract 393 from 596 to get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

On to step 9:
The number 393 fits into 2030 5 times, leaving a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 197171.5
If we subtract 1965 from 2030, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 10:
The number 393 fits into 650 1 times, leaving a remainder of 257.
The next digit of our result is 1. 
Result so far: 197171.51
The remainder is 257 after subtracting 393 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

On to step 11:
2570 divided by 393 is 6 with a remainder of 212.
The number 6 becomes the next digit in our result. 
Result so far: 197171.516
The remainder is 212 after subtracting 2358 from 2570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 12:
2120 divided by 393 is 5 with a remainder of 155.
Put 5 as the next digit of the answer. 
Result so far: 197171.5165
Deduct 1965 from 2120 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 13:
When dividing 1550 by 393, we get 3 with a remainder of 371.
The number 3 becomes the next digit in our result. 
Result so far: 197171.51653
Subtract 1179 from 1550 to get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Moving on to step 14:
The number 393 fits into 3710 9 times, leaving a remainder of 173.
Put 9 as the next digit of the answer. 
Result so far: 197171.516539
Subtracting 3537 from 3710 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 15:
1730 divided by 393 is 4 with a remainder of 158.
Use 4 as the next digit of our solution. 
Result so far: 197171.5165394
Subtracting 1572 from 1730 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 16:
393 can be fit into 1580 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 197171.51653944
If we take 1572 away from 1580, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 197171.51653944 with a remainder of 8e-09.
