99472178 ÷ 556 
We want to figure out the number of times 99472178 can be divided by 556.

On to step 1:
556 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 556

On to step 2:
When dividing 99 by 556, we get 0 with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Grab the next digit (4) from the dividend, add it to 99, then carry on: 994 / 556

Going ahead to step 3:
When dividing 994 by 556, we get 1 with a remainder of 438.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 556 from 994, we get 438.
Bring next digit (7) of the dividend behind the 438 and repeat the process: 4387 / 556

Let's proceed to step 4:
556 can be fit into 4387 7 times, resulting in a remainder of 495.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 3892 from 4387 and we're left with 495.
Grab the next digit (2) from the dividend, add it to 495, then carry on: 4952 / 556

On to step 5:
The number 556 fits into 4952 8 times, leaving a remainder of 504.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
The remainder is 504 after subtracting 4448 from 4952.
Include the next digit (1) from the dividend after 504, then repeat: 5041 / 556

Step 6:
The number 556 fits into 5041 9 times, leaving a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 1789.0
Subtracting 5004 from 5041 leaves us with 37.
Include the next digit (7) from the dividend after 37, then repeat: 377 / 556

Advancing to step 7:
556 can be fit into 377 0 times, resulting in a remainder of 377.
The number 0 becomes the next digit in our result. 
Result so far: 17890.0
Subtract 0 from 377 to get 377.
Include the next digit (8) from the dividend after 377, then repeat: 3778 / 556

Going ahead to step 8:
3778 divided by 556 is 6 with a remainder of 442.
The number 6 becomes the next digit in our result. 
Result so far: 178906.0
If we subtract 3336 from 3778, we get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Advancing to step 9:
The number 556 fits into 4420 7 times, leaving a remainder of 528.
The number 7 becomes the next digit in our result. 
Result so far: 178906.7
If we subtract 3892 from 4420, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Going ahead to step 10:
If we divide 5280 by 556, we get 9 and a remainder of 276.
Record the quotient 9 as the next digit in the result. 
Result so far: 178906.79
Deduct 5004 from 5280 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Going ahead to step 11:
556 can be fit into 2760 4 times, resulting in a remainder of 536.
Put 4 as the next digit of the answer. 
Result so far: 178906.794
If we take 2224 away from 2760, we end up with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Let's proceed to step 12:
5360 divided by 556 is 9 with a remainder of 356.
The next digit of our result is 9. 
Result so far: 178906.7949
If we subtract 5004 from 5360, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 13:
When dividing 3560 by 556, we get 6 with a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 178906.79496
Subtracting 3336 from 3560 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 14:
The number 556 fits into 2240 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 178906.794964
Subtract 2224 from 2240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 15:
The number 556 fits into 160 0 times, leaving a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 178906.794964
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 16:
556 goes into 1600 2 times with a remainder of 488.
Put 2 as the next digit of the answer. 
Result so far: 178906.79496402
Deduct 1112 from 1600 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

The final result is 178906.79496402 with a remainder of 4.88e-07.
