38403451 divided by 577 
We're looking to find how many times 577 goes into 38403451.

Step 1:
When dividing 3 by 577, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 577

Advancing to step 2:
When dividing 38 by 577, we get 0 with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 577

Let's proceed to step 3:
577 goes into 384 0 times with a remainder of 384.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 384, we end up with 384.
Include the next digit (0) from the dividend after 384, then repeat: 3840 / 577

On to step 4:
3840 divided by 577 is 6 with a remainder of 378.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 3462 from 3840 to get 378.
Include the next digit (3) from the dividend after 378, then repeat: 3783 / 577

Going ahead to step 5:
When dividing 3783 by 577, we get 6 with a remainder of 321.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
If we take 3462 away from 3783, we end up with 321.
Append the next digit (4) from the dividend to 321 and continue with: 3214 / 577

Step 6:
3214 divided by 577 is 5 with a remainder of 329.
Use 5 as the next digit of our solution. 
Result so far: 665.0
Subtract 2885 from 3214 to get 329.
Bring next digit (5) of the dividend behind the 329 and repeat the process: 3295 / 577

Going ahead to step 7:
577 can be fit into 3295 5 times, resulting in a remainder of 410.
Use 5 as the next digit of our solution. 
Result so far: 6655.0
Subtracting 2885 from 3295 leaves us with 410.
Fetch the next digit (1) from the dividend, attach it to 410 and continue: 4101 / 577

Moving on to step 8:
577 can be fit into 4101 7 times, resulting in a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 66557.0
Deduct 4039 from 4101 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
If we divide 620 by 577, we get 1 and a remainder of 43.
Record the quotient 1 as the next digit in the result. 
Result so far: 66557.1
If we take 577 away from 620, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 10:
When dividing 430 by 577, we get 0 with a remainder of 430.
Write down 0 as next digit of the result. 
Result so far: 66557.1
Subtract 0 from 430 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 11:
577 goes into 4300 7 times with a remainder of 261.
Put 7 as the next digit of the answer. 
Result so far: 66557.107
Deduct 4039 from 4300 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Step 12:
When dividing 2610 by 577, we get 4 with a remainder of 302.
Put 4 as the next digit of the answer. 
Result so far: 66557.1074
The remainder is 302 after subtracting 2308 from 2610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 13:
When dividing 3020 by 577, we get 5 with a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 66557.10745
If we subtract 2885 from 3020, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 14:
1350 divided by 577 is 2 with a remainder of 196.
Write down 2 as next digit of the result. 
Result so far: 66557.107452
Subtract 1154 from 1350 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 15:
577 can be fit into 1960 3 times, resulting in a remainder of 229.
The next digit of our result is 3. 
Result so far: 66557.1074523
If we take 1731 away from 1960, we end up with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

On to step 16:
577 can be fit into 2290 3 times, resulting in a remainder of 559.
The next digit of our result is 3. 
Result so far: 66557.10745233
Subtract 1731 from 2290 to get 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

In conclusion, the division gives 66557.10745233 with a balance of 5.59e-07.
