77355297 ÷ 406 
Let's see how many times 406 fits into 77355297.

Let's proceed to step 1:
406 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 406

Moving on to step 2:
77 divided by 406 is 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 406

Moving on to step 3:
773 divided by 406 is 1 with a remainder of 367.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 406 from 773, we get 367.
Grab the next digit (5) from the dividend, add it to 367, then carry on: 3675 / 406

Let's proceed to step 4:
The number 406 fits into 3675 9 times, leaving a remainder of 21.
The next digit of our result is 9. 
Result so far: 19.0
If we take 3654 away from 3675, we end up with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 406

Advancing to step 5:
215 divided by 406 is 0 with a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
Deduct 0 from 215 and we're left with 215.
Grab the next digit (2) from the dividend, add it to 215, then carry on: 2152 / 406

Step 6:
406 goes into 2152 5 times with a remainder of 122.
The number 5 becomes the next digit in our result. 
Result so far: 1905.0
The remainder is 122 after subtracting 2030 from 2152.
Grab the next digit (9) from the dividend, add it to 122, then carry on: 1229 / 406

Let's proceed to step 7:
When dividing 1229 by 406, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 19053.0
Subtracting 1218 from 1229 leaves us with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 406

Going ahead to step 8:
406 goes into 117 0 times with a remainder of 117.
The number 0 becomes the next digit in our result. 
Result so far: 190530.0
Subtract 0 from 117 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 9:
If we divide 1170 by 406, we get 2 and a remainder of 358.
Use 2 as the next digit of our solution. 
Result so far: 190530.2
Subtracting 812 from 1170 leaves us with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 10:
When dividing 3580 by 406, we get 8 with a remainder of 332.
The next digit of our result is 8. 
Result so far: 190530.28
Deduct 3248 from 3580 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 11:
3320 divided by 406 is 8 with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 190530.288
If we take 3248 away from 3320, we end up 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.

After the division, we end up with 190530.288 and a remainder of 0.0072.
