Let's divide 160518 by 21
We want to figure out the number of times 160518 can be divided by 21.

Moving on to step 1:
21 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 21

Step 2:
21 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 21

Let's proceed to step 3:
The number 21 fits into 160 7 times, leaving a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 147 from 160 to get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 21

Let's proceed to step 4:
135 divided by 21 is 6 with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
The remainder is 9 after subtracting 126 from 135.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 21

Advancing to step 5:
91 divided by 21 is 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 764.0
Subtract 84 from 91 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 21

Moving on to step 6:
If we divide 78 by 21, we get 3 and a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 7643.0
Subtracting 63 from 78 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
21 goes into 150 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7643.7
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
30 divided by 21 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 7643.71
Subtracting 21 from 30 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
90 divided by 21 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 7643.714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 7643.7142
The remainder is 18 after subtracting 42 from 60.
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 11:
When dividing 180 by 21, we get 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 7643.71428
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
21 goes into 120 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 7643.714285
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 7643.7142857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
30 divided by 21 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 7643.71428571
Deduct 21 from 30 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 7643.71428571, with a leftover of 9e-09.
