21161151 divided by 149 
Our goal is to divide 21161151 by 149.

Moving on to step 1:
149 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 149

Let's proceed to step 2:
If we divide 21 by 149, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 149

Moving on to step 3:
If we divide 211 by 149, we get 1 and a remainder of 62.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 149 from 211 leaves us with 62.
Append the next digit (6) from the dividend to 62 and continue with: 626 / 149

Let's proceed to step 4:
When dividing 626 by 149, we get 4 with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we take 596 away from 626, we end up with 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 149

Moving on to step 5:
The number 149 fits into 301 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 142.0
Subtract 298 from 301 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 149

On to step 6:
149 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 1420.0
If we subtract 0 from 31, we get 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 149

On to step 7:
315 divided by 149 is 2 with a remainder of 17.
The next digit of our result is 2. 
Result so far: 14202.0
If we take 298 away from 315, we end up with 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 149

Advancing to step 8:
The number 149 fits into 171 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 142021.0
Subtracting 149 from 171 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
149 goes into 220 1 times with a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 142021.1
The remainder is 71 after subtracting 149 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 10:
149 can be fit into 710 4 times, resulting in a remainder of 114.
Put 4 as the next digit of the answer. 
Result so far: 142021.14
Subtract 596 from 710 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 11:
The number 149 fits into 1140 7 times, leaving a remainder of 97.
The number 7 becomes the next digit in our result. 
Result so far: 142021.147
Subtracting 1043 from 1140 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 12:
970 divided by 149 is 6 with a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 142021.1476
Subtract 894 from 970 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 13:
149 can be fit into 760 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 142021.14765
If we take 745 away from 760, 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.

Let's proceed to step 14:
149 goes into 150 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 142021.147651
If we subtract 149 from 150, 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.

Going ahead to step 15:
149 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 142021.147651
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.

Going ahead to step 16:
149 goes into 100 0 times with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 142021.147651
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 142021.147651, with a leftover of 1e-07.
