3993738 divided by 558 
We're looking to find how many times 558 goes into 3993738.

Let's proceed to step 1:
The number 558 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 558

Step 2:
39 divided by 558 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 558

Moving on to step 3:
399 divided by 558 is 0 with a remainder of 399.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 399 and we're left with 399.
Append the next digit (3) from the dividend to 399 and continue with: 3993 / 558

Let's proceed to step 4:
558 can be fit into 3993 7 times, resulting in a remainder of 87.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 87 after subtracting 3906 from 3993.
Append the next digit (7) from the dividend to 87 and continue with: 877 / 558

Moving on to step 5:
If we divide 877 by 558, we get 1 and a remainder of 319.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Subtract 558 from 877 to get 319.
Bring next digit (3) of the dividend behind the 319 and repeat the process: 3193 / 558

On to step 6:
The number 558 fits into 3193 5 times, leaving a remainder of 403.
Write down 5 as next digit of the result. 
Result so far: 715.0
Subtracting 2790 from 3193 leaves us with 403.
Fetch the next digit (8) from the dividend, attach it to 403 and continue: 4038 / 558

Going ahead to step 7:
4038 divided by 558 is 7 with a remainder of 132.
Use 7 as the next digit of our solution. 
Result so far: 7157.0
If we subtract 3906 from 4038, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 8:
When dividing 1320 by 558, we get 2 with a remainder of 204.
Put 2 as the next digit of the answer. 
Result so far: 7157.2
If we take 1116 away from 1320, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 9:
The number 558 fits into 2040 3 times, leaving a remainder of 366.
Use 3 as the next digit of our solution. 
Result so far: 7157.23
If we subtract 1674 from 2040, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 10:
When dividing 3660 by 558, we get 6 with a remainder of 312.
The number 6 becomes the next digit in our result. 
Result so far: 7157.236
Subtracting 3348 from 3660 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 11:
If we divide 3120 by 558, we get 5 and a remainder of 330.
The number 5 becomes the next digit in our result. 
Result so far: 7157.2365
Deduct 2790 from 3120 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 12:
558 can be fit into 3300 5 times, resulting in a remainder of 510.
Record the quotient 5 as the next digit in the result. 
Result so far: 7157.23655
Subtracting 2790 from 3300 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

The final result is 7157.23655 with a remainder of 0.00051.
