Step 1:
5 divided by 921 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 921

Advancing to step 2:
The number 921 fits into 53 0 times, leaving a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 921

Going ahead to step 3:
921 can be fit into 537 0 times, resulting in a remainder of 537.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 537 leaves us with 537.
Bring next digit (7) of the dividend behind the 537 and repeat the process: 5377 / 921

Let's proceed to step 4:
When dividing 5377 by 921, we get 5 with a remainder of 772.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 4605 from 5377, we get 772.
Take the next digit (8) from the dividend and append it to 772, then repeat: 7728 / 921

Let's proceed to step 5:
921 goes into 7728 8 times with a remainder of 360.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
If we take 7368 away from 7728, we end up with 360.
Grab the next digit (1) from the dividend, add it to 360, then carry on: 3601 / 921

Moving on to step 6:
If we divide 3601 by 921, we get 3 and a remainder of 838.
Write down 3 as next digit of the result. 
Result so far: 583.0
If we take 2763 away from 3601, we end up with 838.
Grab the next digit (4) from the dividend, add it to 838, then carry on: 8384 / 921

Advancing to step 7:
The number 921 fits into 8384 9 times, leaving a remainder of 95.
Put 9 as the next digit of the answer. 
Result so far: 5839.0
The remainder is 95 after subtracting 8289 from 8384.
Fetch the next digit (8) from the dividend, attach it to 95 and continue: 958 / 921

Let's proceed to step 8:
If we divide 958 by 921, we get 1 and a remainder of 37.
The next digit of our result is 1. 
Result so far: 58391.0
Deduct 921 from 958 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 9:
The number 921 fits into 370 0 times, leaving a remainder of 370.
Put 0 as the next digit of the answer. 
Result so far: 58391.0
Subtract 0 from 370 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 10:
921 goes into 3700 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 58391.04
The remainder is 16 after subtracting 3684 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
If we divide 160 by 921, we get 0 and a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 58391.04
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 12:
The number 921 fits into 1600 1 times, leaving a remainder of 679.
The next digit of our result is 1. 
Result so far: 58391.0401
If we take 921 away from 1600, we end up with 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Step 13:
When dividing 6790 by 921, we get 7 with a remainder of 343.
Record the quotient 7 as the next digit in the result. 
Result so far: 58391.04017
If we subtract 6447 from 6790, we get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

On to step 14:
When dividing 3430 by 921, we get 3 with a remainder of 667.
Use 3 as the next digit of our solution. 
Result so far: 58391.040173
Deduct 2763 from 3430 and we're left with 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

On to step 15:
The number 921 fits into 6670 7 times, leaving a remainder of 223.
The number 7 becomes the next digit in our result. 
Result so far: 58391.0401737
If we subtract 6447 from 6670, we get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Advancing to step 16:
2230 divided by 921 is 2 with a remainder of 388.
Record the quotient 2 as the next digit in the result. 
Result so far: 58391.04017372
If we take 1842 away from 2230, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Our division results in 58391.04017372 with a remaining 3.88e-07.
