We're dividing 30915903 by 879 
Our goal is to divide 30915903 by 879.

Let's proceed to step 1:
The number 879 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 879

Let's proceed to step 2:
879 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 879

Advancing to step 3:
309 divided by 879 is 0 with a remainder of 309.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 309 to get 309.
Fetch the next digit (1) from the dividend, attach it to 309 and continue: 3091 / 879

Step 4:
If we divide 3091 by 879, we get 3 and a remainder of 454.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 2637 from 3091 to get 454.
Include the next digit (5) from the dividend after 454, then repeat: 4545 / 879

Let's proceed to step 5:
879 can be fit into 4545 5 times, resulting in a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we subtract 4395 from 4545, we get 150.
Append the next digit (9) from the dividend to 150 and continue with: 1509 / 879

Let's proceed to step 6:
The number 879 fits into 1509 1 times, leaving a remainder of 630.
Put 1 as the next digit of the answer. 
Result so far: 351.0
If we subtract 879 from 1509, we get 630.
Bring next digit (0) of the dividend behind the 630 and repeat the process: 6300 / 879

Moving on to step 7:
879 can be fit into 6300 7 times, resulting in a remainder of 147.
Write down 7 as next digit of the result. 
Result so far: 3517.0
If we take 6153 away from 6300, we end up with 147.
Take the next digit (3) from the dividend and append it to 147, then repeat: 1473 / 879

On to step 8:
879 goes into 1473 1 times with a remainder of 594.
Record the quotient 1 as the next digit in the result. 
Result so far: 35171.0
If we subtract 879 from 1473, we get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Step 9:
879 goes into 5940 6 times with a remainder of 666.
Write down 6 as next digit of the result. 
Result so far: 35171.6
Subtract 5274 from 5940 to get 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Moving on to step 10:
The number 879 fits into 6660 7 times, leaving a remainder of 507.
The next digit of our result is 7. 
Result so far: 35171.67
Subtract 6153 from 6660 to get 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Let's proceed to step 11:
The number 879 fits into 5070 5 times, leaving a remainder of 675.
The number 5 becomes the next digit in our result. 
Result so far: 35171.675
Deduct 4395 from 5070 and we're left with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Going ahead to step 12:
879 goes into 6750 7 times with a remainder of 597.
Put 7 as the next digit of the answer. 
Result so far: 35171.6757
Deduct 6153 from 6750 and we're left with 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Let's proceed to step 13:
5970 divided by 879 is 6 with a remainder of 696.
The next digit of our result is 6. 
Result so far: 35171.67576
If we subtract 5274 from 5970, we get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Advancing to step 14:
When dividing 6960 by 879, we get 7 with a remainder of 807.
The number 7 becomes the next digit in our result. 
Result so far: 35171.675767
Deduct 6153 from 6960 and we're left with 807.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8070, and continue the process.

Let's proceed to step 15:
879 can be fit into 8070 9 times, resulting in a remainder of 159.
Put 9 as the next digit of the answer. 
Result so far: 35171.6757679
If we subtract 7911 from 8070, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 16:
879 can be fit into 1590 1 times, resulting in a remainder of 711.
Record the quotient 1 as the next digit in the result. 
Result so far: 35171.67576791
The remainder is 711 after subtracting 879 from 1590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

In conclusion, the division gives 35171.67576791 with a balance of 7.11e-07.
