We divide 870151 by 29
We want to figure out the number of times 870151 can be divided by 29.

Advancing to step 1:
29 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 29

Going ahead to step 2:
If we divide 87 by 29, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 87 from 87 to get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 29

Going ahead to step 3:
If we divide 0 by 29, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30.0
The remainder is 0 after subtracting 0 from 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 29

Moving on to step 4:
1 divided by 29 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 300.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 29

On to step 5:
The number 29 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 3000.0
If we subtract 0 from 15, we get 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 29

On to step 6:
29 goes into 151 5 times with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 30005.0
Deduct 145 from 151 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
If we divide 60 by 29, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 30005.2
Subtracting 58 from 60 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 29, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 30005.2
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
29 goes into 200 6 times with a remainder of 26.
The next digit of our result is 6. 
Result so far: 30005.206
The remainder is 26 after subtracting 174 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
When dividing 260 by 29, we get 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 30005.2068
Deduct 232 from 260 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
29 goes into 280 9 times with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 30005.20689
Subtract 261 from 280 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
190 divided by 29 is 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 30005.206896
Deduct 174 from 190 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
29 goes into 160 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 30005.2068965
Deduct 145 from 160 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
When dividing 150 by 29, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 30005.20689655
If we take 145 away from 150, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 30005.20689655, with a leftover of 5e-09.
