We're dividing 12093220 by 159 
We want to figure out the number of times 12093220 can be divided by 159.

Step 1:
When dividing 1 by 159, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 159

On to step 2:
The number 159 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 159

Step 3:
When dividing 120 by 159, we get 0 with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 120, we get 120.
Take the next digit (9) from the dividend and append it to 120, then repeat: 1209 / 159

Step 4:
1209 divided by 159 is 7 with a remainder of 96.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 1113 from 1209 and we're left with 96.
Grab the next digit (3) from the dividend, add it to 96, then carry on: 963 / 159

Advancing to step 5:
159 goes into 963 6 times with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtract 954 from 963 to get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 159

On to step 6:
159 goes into 92 0 times with a remainder of 92.
Use 0 as the next digit of our solution. 
Result so far: 760.0
Subtract 0 from 92 to get 92.
Bring next digit (2) of the dividend behind the 92 and repeat the process: 922 / 159

Advancing to step 7:
The number 159 fits into 922 5 times, leaving a remainder of 127.
Put 5 as the next digit of the answer. 
Result so far: 7605.0
Subtracting 795 from 922 leaves us with 127.
Fetch the next digit (0) from the dividend, attach it to 127 and continue: 1270 / 159

Let's proceed to step 8:
159 can be fit into 1270 7 times, resulting in a remainder of 157.
Use 7 as the next digit of our solution. 
Result so far: 76057.0
If we take 1113 away from 1270, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 9:
When dividing 1570 by 159, we get 9 with a remainder of 139.
Write down 9 as next digit of the result. 
Result so far: 76057.9
Subtracting 1431 from 1570 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 10:
The number 159 fits into 1390 8 times, leaving a remainder of 118.
Put 8 as the next digit of the answer. 
Result so far: 76057.98
Subtracting 1272 from 1390 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 11:
The number 159 fits into 1180 7 times, leaving a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 76057.987
The remainder is 67 after subtracting 1113 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 12:
670 divided by 159 is 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 76057.9874
Subtracting 636 from 670 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
159 goes into 340 2 times with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 76057.98742
Deduct 318 from 340 and we're left 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.

Step 14:
The number 159 fits into 220 1 times, leaving a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 76057.987421
If we take 159 away from 220, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 15:
159 goes into 610 3 times with a remainder of 133.
Record the quotient 3 as the next digit in the result. 
Result so far: 76057.9874213
Subtracting 477 from 610 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

On to step 16:
159 can be fit into 1330 8 times, resulting in a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 76057.98742138
If we subtract 1272 from 1330, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The quotient of the division is 76057.98742138, and the remainder is 5.8e-08.
