57487778 divided by 446 
We want to figure out the number of times 57487778 can be divided by 446.

Step 1:
If we divide 5 by 446, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 446

On to step 2:
446 goes into 57 0 times with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Grab the next digit (4) from the dividend, add it to 57, then carry on: 574 / 446

Let's proceed to step 3:
The number 446 fits into 574 1 times, leaving a remainder of 128.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 446 from 574 to get 128.
Fetch the next digit (8) from the dividend, attach it to 128 and continue: 1288 / 446

Advancing to step 4:
The number 446 fits into 1288 2 times, leaving a remainder of 396.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 892 from 1288, we get 396.
Append the next digit (7) from the dividend to 396 and continue with: 3967 / 446

Going ahead to step 5:
The number 446 fits into 3967 8 times, leaving a remainder of 399.
Use 8 as the next digit of our solution. 
Result so far: 128.0
Subtracting 3568 from 3967 leaves us with 399.
Fetch the next digit (7) from the dividend, attach it to 399 and continue: 3997 / 446

Moving on to step 6:
446 goes into 3997 8 times with a remainder of 429.
The number 8 becomes the next digit in our result. 
Result so far: 1288.0
If we take 3568 away from 3997, we end up with 429.
Fetch the next digit (7) from the dividend, attach it to 429 and continue: 4297 / 446

On to step 7:
When dividing 4297 by 446, we get 9 with a remainder of 283.
Put 9 as the next digit of the answer. 
Result so far: 12889.0
Deduct 4014 from 4297 and we're left with 283.
Grab the next digit (8) from the dividend, add it to 283, then carry on: 2838 / 446

Going ahead to step 8:
2838 divided by 446 is 6 with a remainder of 162.
Put 6 as the next digit of the answer. 
Result so far: 128896.0
The remainder is 162 after subtracting 2676 from 2838.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 9:
446 can be fit into 1620 3 times, resulting in a remainder of 282.
Write down 3 as next digit of the result. 
Result so far: 128896.3
The remainder is 282 after subtracting 1338 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 10:
2820 divided by 446 is 6 with a remainder of 144.
Put 6 as the next digit of the answer. 
Result so far: 128896.36
If we subtract 2676 from 2820, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 11:
When dividing 1440 by 446, we get 3 with a remainder of 102.
Put 3 as the next digit of the answer. 
Result so far: 128896.363
Subtract 1338 from 1440 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 12:
1020 divided by 446 is 2 with a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 128896.3632
If we subtract 892 from 1020, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 13:
If we divide 1280 by 446, we get 2 and a remainder of 388.
The next digit of our result is 2. 
Result so far: 128896.36322
If we take 892 away from 1280, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

After the division, we end up with 128896.36322 and a remainder of 0.000388.
