162475 divided by 21 
We're looking to find how many times 21 goes into 162475.

On to step 1:
If we divide 1 by 21, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 21

Let's proceed to step 2:
If we divide 16 by 21, we get 0 and a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 21

Advancing to step 3:
The number 21 fits into 162 7 times, leaving a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 15 after subtracting 147 from 162.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 21

Step 4:
When dividing 154 by 21, we get 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 77.0
If we take 147 away from 154, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 21

Going ahead to step 5:
77 divided by 21 is 3 with a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 773.0
Deduct 63 from 77 and we're left with 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 21

On to step 6:
21 goes into 145 6 times with a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 7736.0
Subtracting 126 from 145 leaves us with 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 7:
If we divide 190 by 21, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 7736.9
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 7736.9
If we take 0 away from 10, 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.

Step 9:
21 goes into 100 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 7736.904
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
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: 7736.9047
If we subtract 147 from 160, we 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.

Step 11:
130 divided by 21 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 7736.90476
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.

Let's proceed to step 12:
If we divide 40 by 21, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 7736.904761
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
When dividing 190 by 21, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 7736.9047619
Deduct 189 from 190 and we're left 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 14:
The number 21 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 7736.9047619
Subtracting 0 from 10 leaves us 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.

The final outcome is 7736.9047619, with a leftover of 1e-08.
