34450129 ÷ 869 
We're looking to find how many times 869 goes into 34450129.

Moving on to step 1:
If we divide 3 by 869, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 869

Moving on to step 2:
If we divide 34 by 869, we get 0 and a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 869

Advancing to step 3:
The number 869 fits into 344 0 times, leaving a remainder of 344.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 344 after subtracting 0 from 344.
Include the next digit (5) from the dividend after 344, then repeat: 3445 / 869

Step 4:
869 goes into 3445 3 times with a remainder of 838.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 2607 away from 3445, we end up with 838.
Fetch the next digit (0) from the dividend, attach it to 838 and continue: 8380 / 869

Advancing to step 5:
869 can be fit into 8380 9 times, resulting in a remainder of 559.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we subtract 7821 from 8380, we get 559.
Bring next digit (1) of the dividend behind the 559 and repeat the process: 5591 / 869

Let's proceed to step 6:
If we divide 5591 by 869, we get 6 and a remainder of 377.
The next digit of our result is 6. 
Result so far: 396.0
Subtracting 5214 from 5591 leaves us with 377.
Take the next digit (2) from the dividend and append it to 377, then repeat: 3772 / 869

Advancing to step 7:
When dividing 3772 by 869, we get 4 with a remainder of 296.
The number 4 becomes the next digit in our result. 
Result so far: 3964.0
Deduct 3476 from 3772 and we're left with 296.
Fetch the next digit (9) from the dividend, attach it to 296 and continue: 2969 / 869

Going ahead to step 8:
869 can be fit into 2969 3 times, resulting in a remainder of 362.
Use 3 as the next digit of our solution. 
Result so far: 39643.0
The remainder is 362 after subtracting 2607 from 2969.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Advancing to step 9:
The number 869 fits into 3620 4 times, leaving a remainder of 144.
Write down 4 as next digit of the result. 
Result so far: 39643.4
Subtracting 3476 from 3620 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 10:
1440 divided by 869 is 1 with a remainder of 571.
Write down 1 as next digit of the result. 
Result so far: 39643.41
If we subtract 869 from 1440, we get 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Let's proceed to step 11:
When dividing 5710 by 869, we get 6 with a remainder of 496.
Put 6 as the next digit of the answer. 
Result so far: 39643.416
The remainder is 496 after subtracting 5214 from 5710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Let's proceed to step 12:
869 can be fit into 4960 5 times, resulting in a remainder of 615.
Use 5 as the next digit of our solution. 
Result so far: 39643.4165
If we take 4345 away from 4960, we end up with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Going ahead to step 13:
If we divide 6150 by 869, we get 7 and a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 39643.41657
Subtracting 6083 from 6150 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 14:
869 can be fit into 670 0 times, resulting in a remainder of 670.
Use 0 as the next digit of our solution. 
Result so far: 39643.41657
If we subtract 0 from 670, we get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Advancing to step 15:
When dividing 6700 by 869, we get 7 with a remainder of 617.
Put 7 as the next digit of the answer. 
Result so far: 39643.4165707
If we take 6083 away from 6700, we end up with 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Moving on to step 16:
6170 divided by 869 is 7 with a remainder of 87.
The next digit of our result is 7. 
Result so far: 39643.41657077
The remainder is 87 after subtracting 6083 from 6170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

The final outcome is 39643.41657077, with a leftover of 8.7e-08.
