1143137 divided by 869 
We want to figure out the number of times 1143137 can be divided by 869.

Step 1:
If we divide 1 by 869, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 869

On to step 2:
If we divide 11 by 869, we get 0 and a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 869

Advancing to step 3:
869 goes into 114 0 times with a remainder of 114.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 114 to get 114.
Bring next digit (3) of the dividend behind the 114 and repeat the process: 1143 / 869

Going ahead to step 4:
869 can be fit into 1143 1 times, resulting in a remainder of 274.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 274 after subtracting 869 from 1143.
Grab the next digit (1) from the dividend, add it to 274, then carry on: 2741 / 869

Let's proceed to step 5:
869 can be fit into 2741 3 times, resulting in a remainder of 134.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 2607 away from 2741, we end up with 134.
Take the next digit (3) from the dividend and append it to 134, then repeat: 1343 / 869

Let's proceed to step 6:
869 can be fit into 1343 1 times, resulting in a remainder of 474.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
Subtracting 869 from 1343 leaves us with 474.
Include the next digit (7) from the dividend after 474, then repeat: 4747 / 869

Moving on to step 7:
869 can be fit into 4747 5 times, resulting in a remainder of 402.
Use 5 as the next digit of our solution. 
Result so far: 1315.0
If we subtract 4345 from 4747, we get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Advancing to step 8:
4020 divided by 869 is 4 with a remainder of 544.
Record the quotient 4 as the next digit in the result. 
Result so far: 1315.4
Deduct 3476 from 4020 and we're left with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 9:
When dividing 5440 by 869, we get 6 with a remainder of 226.
Put 6 as the next digit of the answer. 
Result so far: 1315.46
Deduct 5214 from 5440 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 10:
If we divide 2260 by 869, we get 2 and a remainder of 522.
The number 2 becomes the next digit in our result. 
Result so far: 1315.462
If we subtract 1738 from 2260, we get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

On to step 11:
869 goes into 5220 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 1315.4626
If we subtract 5214 from 5220, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
869 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 1315.4626
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.

Let's proceed to step 13:
When dividing 600 by 869, we get 0 with a remainder of 600.
Record the quotient 0 as the next digit in the result. 
Result so far: 1315.4626
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final outcome is 1315.4626, with a leftover of 6e-05.
