We look at the division of 141837 by 21 
Our goal is to divide 141837 by 21.

Going ahead 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
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 21

On to step 2:
If we divide 14 by 21, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 21

Advancing to step 3:
141 divided by 21 is 6 with a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 15 after subtracting 126 from 141.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 21

Going ahead to step 4:
When dividing 158 by 21, we get 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 67.0
Deduct 147 from 158 and we're left with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 21

On to step 5:
113 divided by 21 is 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 675.0
Subtract 105 from 113 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 21

Let's proceed to step 6:
The number 21 fits into 87 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 6754.0
If we subtract 84 from 87, we 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.

On to step 7:
If we divide 30 by 21, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 6754.1
Subtract 21 from 30 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 6754.14
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.

Moving on to step 9:
The number 21 fits into 60 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 6754.142
Subtract 42 from 60 to get 18.
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 10:
180 divided by 21 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 6754.1428
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
21 goes into 120 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 6754.14285
If we take 105 away from 120, we end up 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.

Advancing to step 12:
When dividing 150 by 21, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 6754.142857
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 13:
The number 21 fits into 30 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 6754.1428571
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.

Advancing to step 14:
21 goes into 90 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 6754.14285714
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 6754.14285714 with a remainder of 6e-09.
