3910354 ÷ 558 
Our goal is to divide 3910354 by 558.

On to step 1:
558 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
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

Let's proceed to step 2:
558 can be fit into 39 0 times, resulting in a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 558

Advancing to step 3:
558 can be fit into 391 0 times, resulting in a remainder of 391.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 391 to get 391.
Grab the next digit (0) from the dividend, add it to 391, then carry on: 3910 / 558

Going ahead to step 4:
If we divide 3910 by 558, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 3906 away from 3910, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 558

Advancing to step 5:
When dividing 43 by 558, we get 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
Deduct 0 from 43 and we're left with 43.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 558

Let's proceed to step 6:
558 goes into 435 0 times with a remainder of 435.
Record the quotient 0 as the next digit in the result. 
Result so far: 700.0
Subtract 0 from 435 to get 435.
Take the next digit (4) from the dividend and append it to 435, then repeat: 4354 / 558

Step 7:
If we divide 4354 by 558, we get 7 and a remainder of 448.
Use 7 as the next digit of our solution. 
Result so far: 7007.0
If we subtract 3906 from 4354, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Let's proceed to step 8:
When dividing 4480 by 558, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 7007.8
The remainder is 16 after subtracting 4464 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
If we divide 160 by 558, we get 0 and a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 7007.8
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 10:
If we divide 1600 by 558, we get 2 and a remainder of 484.
Record the quotient 2 as the next digit in the result. 
Result so far: 7007.802
Subtracting 1116 from 1600 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Step 11:
4840 divided by 558 is 8 with a remainder of 376.
Use 8 as the next digit of our solution. 
Result so far: 7007.8028
Subtracting 4464 from 4840 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 12:
558 goes into 3760 6 times with a remainder of 412.
Write down 6 as next digit of the result. 
Result so far: 7007.80286
Subtracting 3348 from 3760 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 13:
558 goes into 4120 7 times with a remainder of 214.
The number 7 becomes the next digit in our result. 
Result so far: 7007.802867
Subtracting 3906 from 4120 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 14:
If we divide 2140 by 558, we get 3 and a remainder of 466.
The number 3 becomes the next digit in our result. 
Result so far: 7007.8028673
Subtracting 1674 from 2140 leaves us with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

On to step 15:
When dividing 4660 by 558, we get 8 with a remainder of 196.
The number 8 becomes the next digit in our result. 
Result so far: 7007.80286738
If we subtract 4464 from 4660, we 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.

The final outcome is 7007.80286738, with a leftover of 1.96e-07.
