21368838 ÷ 141 
We want to divide 21368838 by 141.

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

On to step 2:
141 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 141

On to step 3:
If we divide 213 by 141, we get 1 and a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 141 from 213 leaves us with 72.
Fetch the next digit (6) from the dividend, attach it to 72 and continue: 726 / 141

Moving on to step 4:
141 can be fit into 726 5 times, resulting in a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 705 from 726, we get 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 141

On to step 5:
218 divided by 141 is 1 with a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 151.0
Subtracting 141 from 218 leaves us with 77.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 141

Going ahead to step 6:
When dividing 778 by 141, we get 5 with a remainder of 73.
The number 5 becomes the next digit in our result. 
Result so far: 1515.0
Deduct 705 from 778 and we're left with 73.
Include the next digit (3) from the dividend after 73, then repeat: 733 / 141

On to step 7:
If we divide 733 by 141, we get 5 and a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 15155.0
Subtract 705 from 733 to get 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 141

Moving on to step 8:
141 can be fit into 288 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 151552.0
If we take 282 away from 288, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
60 divided by 141 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 151552.0
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
The number 141 fits into 600 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 151552.04
The remainder is 36 after subtracting 564 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
If we divide 360 by 141, we get 2 and a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 151552.042
The remainder is 78 after subtracting 282 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 12:
The number 141 fits into 780 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 151552.0425
Subtracting 705 from 780 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 13:
141 goes into 750 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 151552.04255
Subtracting 705 from 750 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 151552.04255, with a leftover of 4.5e-05.
