21849517 ÷ 169 
Our goal is to divide 21849517 by 169.

Going ahead to step 1:
2 divided by 169 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 169

Moving on to step 2:
169 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 169

Going ahead to step 3:
169 can be fit into 218 1 times, resulting in a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 169 from 218 and we're left with 49.
Take the next digit (4) from the dividend and append it to 49, then repeat: 494 / 169

On to step 4:
494 divided by 169 is 2 with a remainder of 156.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 338 from 494 and we're left with 156.
Take the next digit (9) from the dividend and append it to 156, then repeat: 1569 / 169

Let's proceed to step 5:
When dividing 1569 by 169, we get 9 with a remainder of 48.
The next digit of our result is 9. 
Result so far: 129.0
Deduct 1521 from 1569 and we're left with 48.
Fetch the next digit (5) from the dividend, attach it to 48 and continue: 485 / 169

Let's proceed to step 6:
169 goes into 485 2 times with a remainder of 147.
Put 2 as the next digit of the answer. 
Result so far: 1292.0
Subtracting 338 from 485 leaves us with 147.
Take the next digit (1) from the dividend and append it to 147, then repeat: 1471 / 169

Advancing to step 7:
The number 169 fits into 1471 8 times, leaving a remainder of 119.
Write down 8 as next digit of the result. 
Result so far: 12928.0
The remainder is 119 after subtracting 1352 from 1471.
Include the next digit (7) from the dividend after 119, then repeat: 1197 / 169

Moving on to step 8:
169 goes into 1197 7 times with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 129287.0
The remainder is 14 after subtracting 1183 from 1197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
The number 169 fits into 140 0 times, leaving a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 129287.0
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
The number 169 fits into 1400 8 times, leaving a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 129287.08
Deduct 1352 from 1400 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
169 goes into 480 2 times with a remainder of 142.
The next digit of our result is 2. 
Result so far: 129287.082
If we subtract 338 from 480, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 12:
If we divide 1420 by 169, we get 8 and a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 129287.0828
Subtracting 1352 from 1420 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 13:
When dividing 680 by 169, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 129287.08284
Subtract 676 from 680 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
When dividing 40 by 169, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 129287.08284
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 15:
169 goes into 400 2 times with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 129287.0828402
If we take 338 away from 400, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 16:
When dividing 620 by 169, we get 3 with a remainder of 113.
The number 3 becomes the next digit in our result. 
Result so far: 129287.08284023
Deduct 507 from 620 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

The final outcome is 129287.08284023, with a leftover of 1.13e-07.
