603686 ÷ 58 
Our goal is to divide 603686 by 58.

Moving on to step 1:
When dividing 6 by 58, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 58

Advancing to step 2:
When dividing 60 by 58, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 58 from 60 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 58

Let's proceed to step 3:
58 goes into 23 0 times with a remainder of 23.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 23, we end up with 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 58

Going ahead to step 4:
The number 58 fits into 236 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 104.0
If we take 232 away from 236, we end up with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 58

Going ahead to step 5:
If we divide 48 by 58, we get 0 and a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 1040.0
Subtract 0 from 48 to get 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 58

Step 6:
If we divide 486 by 58, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 10408.0
If we subtract 464 from 486, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
58 can be fit into 220 3 times, resulting in a remainder of 46.
Write down 3 as next digit of the result. 
Result so far: 10408.3
The remainder is 46 after subtracting 174 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
If we divide 460 by 58, we get 7 and a remainder of 54.
The next digit of our result is 7. 
Result so far: 10408.37
The remainder is 54 after subtracting 406 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
If we divide 540 by 58, we get 9 and a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 10408.379
If we take 522 away from 540, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
180 divided by 58 is 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 10408.3793
Subtracting 174 from 180 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
58 goes into 60 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 10408.37931
Subtracting 58 from 60 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
58 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 10408.37931
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
If we divide 200 by 58, we get 3 and a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 10408.3793103
If we take 174 away from 200, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
58 can be fit into 260 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 10408.37931034
The remainder is 28 after subtracting 232 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 10408.37931034, with a leftover of 2.8e-08.
