We divide 108658 by 21
Let's see how many times 21 fits into 108658.

Advancing to step 1:
21 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 21

Let's proceed to step 2:
If we divide 10 by 21, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 21

Advancing to step 3:
If we divide 108 by 21, we get 5 and a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 3 after subtracting 105 from 108.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 21

Going ahead to step 4:
21 goes into 36 1 times with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Deduct 21 from 36 and we're left with 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 21

Advancing to step 5:
21 goes into 155 7 times with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 517.0
Deduct 147 from 155 and we're left with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 21

On to step 6:
21 goes into 88 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 5174.0
Deduct 84 from 88 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
40 divided by 21 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 5174.1
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 8:
21 goes into 190 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 5174.19
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 5174.19
Deduct 0 from 10 and we're left 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.

On to step 10:
100 divided by 21 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 5174.1904
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
21 can be fit into 160 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 5174.19047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 5174.190476
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
When dividing 40 by 21, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 5174.1904761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
If we divide 190 by 21, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 5174.19047619
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 5174.19047619, with a leftover of 1e-09.
