Let's divide 948128 by 21
Let's see how many times 21 fits into 948128.

Advancing to step 1:
21 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 21

Going ahead to step 2:
If we divide 94 by 21, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 84 from 94 to get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 21

Going ahead to step 3:
If we divide 108 by 21, we get 5 and a remainder of 3.
The next digit of our result is 5. 
Result so far: 45.0
Subtracting 105 from 108 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 21

Let's proceed to step 4:
If we divide 31 by 21, we get 1 and a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 451.0
Deduct 21 from 31 and we're left with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 21

Going ahead to step 5:
The number 21 fits into 102 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 4514.0
Subtract 84 from 102 to get 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 21

On to step 6:
21 can be fit into 188 8 times, resulting in a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 45148.0
If we take 168 away from 188, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
If we divide 200 by 21, we get 9 and a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 45148.9
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
110 divided by 21 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 45148.95
Subtracting 105 from 110 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
If we divide 50 by 21, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 45148.952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
When dividing 80 by 21, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 45148.9523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
When dividing 170 by 21, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 45148.95238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
21 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 45148.95238
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
When dividing 200 by 21, we get 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 45148.9523809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
110 divided by 21 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 45148.95238095
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 45148.95238095 with a balance of 5e-09.
