19109720 ÷ 159 
We want to figure out the number of times 19109720 can be divided by 159.

Let's proceed to step 1:
159 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 159

Let's proceed to step 2:
19 divided by 159 is 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 159

Moving on to step 3:
159 can be fit into 191 1 times, resulting in a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 159 from 191 and we're left with 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 159

Let's proceed to step 4:
When dividing 320 by 159, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 12.0
If we take 318 away from 320, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 159

Advancing to step 5:
29 divided by 159 is 0 with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 120.0
If we subtract 0 from 29, we get 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 159

On to step 6:
159 goes into 297 1 times with a remainder of 138.
The number 1 becomes the next digit in our result. 
Result so far: 1201.0
Subtracting 159 from 297 leaves us with 138.
Grab the next digit (2) from the dividend, add it to 138, then carry on: 1382 / 159

Let's proceed to step 7:
The number 159 fits into 1382 8 times, leaving a remainder of 110.
Put 8 as the next digit of the answer. 
Result so far: 12018.0
If we subtract 1272 from 1382, we get 110.
Append the next digit (0) from the dividend to 110 and continue with: 1100 / 159

Going ahead to step 8:
159 can be fit into 1100 6 times, resulting in a remainder of 146.
The number 6 becomes the next digit in our result. 
Result so far: 120186.0
If we take 954 away from 1100, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 9:
When dividing 1460 by 159, we get 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 120186.9
If we take 1431 away from 1460, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 10:
159 can be fit into 290 1 times, resulting in a remainder of 131.
The next digit of our result is 1. 
Result so far: 120186.91
Deduct 159 from 290 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Moving on to step 11:
If we divide 1310 by 159, we get 8 and a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 120186.918
If we take 1272 away from 1310, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
159 can be fit into 380 2 times, resulting in a remainder of 62.
The next digit of our result is 2. 
Result so far: 120186.9182
If we subtract 318 from 380, we get 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 13:
The number 159 fits into 620 3 times, leaving a remainder of 143.
Put 3 as the next digit of the answer. 
Result so far: 120186.91823
Subtract 477 from 620 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Step 14:
If we divide 1430 by 159, we get 8 and a remainder of 158.
Write down 8 as next digit of the result. 
Result so far: 120186.918238
Subtracting 1272 from 1430 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 15:
When dividing 1580 by 159, we get 9 with a remainder of 149.
The number 9 becomes the next digit in our result. 
Result so far: 120186.9182389
Subtracting 1431 from 1580 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 16:
159 goes into 1490 9 times with a remainder of 59.
The number 9 becomes the next digit in our result. 
Result so far: 120186.91823899
Subtract 1431 from 1490 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Our division results in 120186.91823899 with a remaining 5.9e-08.
