Let's divide 391021 by 58
We want to divide 391021 by 58.

Advancing to step 1:
The number 58 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 58

Moving on to step 2:
58 goes into 39 0 times with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 58

On to step 3:
58 goes into 391 6 times with a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 348 away from 391, we end up with 43.
Grab the next digit (0) from the dividend, add it to 43, then carry on: 430 / 58

On to step 4:
430 divided by 58 is 7 with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
Subtract 406 from 430 to get 24.
Append the next digit (2) from the dividend to 24 and continue with: 242 / 58

Moving on to step 5:
The number 58 fits into 242 4 times, leaving a remainder of 10.
The next digit of our result is 4. 
Result so far: 674.0
If we subtract 232 from 242, we get 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 58

Let's proceed to step 6:
58 goes into 101 1 times with a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 6741.0
Subtracting 58 from 101 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
430 divided by 58 is 7 with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 6741.7
Subtract 406 from 430 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.

Going ahead to step 8:
The number 58 fits into 240 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 6741.74
Deduct 232 from 240 and we're left 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.

Let's proceed to step 9:
If we divide 80 by 58, we get 1 and a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 6741.741
Subtracting 58 from 80 leaves us 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.

Step 10:
If we divide 220 by 58, we get 3 and a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 6741.7413
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.

Advancing to step 11:
58 can be fit into 460 7 times, resulting in a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 6741.74137
If we take 406 away from 460, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
The number 58 fits into 540 9 times, leaving a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 6741.741379
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.

Going ahead to step 13:
180 divided by 58 is 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 6741.7413793
The remainder is 6 after subtracting 174 from 180.
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 14:
58 can be fit into 60 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 6741.74137931
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.

The quotient of the division is 6741.74137931, and the remainder is 2e-09.
