We look at the division of 390370 by 58 
Our goal is to divide 390370 by 58.

On to step 1:
3 divided by 58 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 58

On to step 2:
If we divide 39 by 58, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 58

On to step 3:
390 divided by 58 is 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 348 from 390 to get 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 58

Let's proceed to step 4:
If we divide 423 by 58, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 67.0
If we take 406 away from 423, we end up with 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 58

Let's proceed to step 5:
The number 58 fits into 177 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 673.0
If we take 174 away from 177, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 58

Advancing to step 6:
58 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 6730.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
When dividing 300 by 58, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 6730.5
If we take 290 away from 300, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 58 fits into 100 1 times, leaving a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 6730.51
If we take 58 away from 100, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
When dividing 420 by 58, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 6730.517
If we subtract 406 from 420, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
58 can be fit into 140 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 6730.5172
Subtract 116 from 140 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
58 can be fit into 240 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 6730.51724
Subtracting 232 from 240 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
58 goes into 80 1 times with a remainder of 22.
The next digit of our result is 1. 
Result so far: 6730.517241
Deduct 58 from 80 and we're left with 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 13:
220 divided by 58 is 3 with a remainder of 46.
The next digit of our result is 3. 
Result so far: 6730.5172413
If we subtract 174 from 220, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 14:
460 divided by 58 is 7 with a remainder of 54.
The next digit of our result is 7. 
Result so far: 6730.51724137
If we subtract 406 from 460, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 6730.51724137 with a remainder of 5.4e-08.
