31433589 ÷ 878 
Let's see how many times 878 fits into 31433589.

Moving on to step 1:
878 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 878

On to step 2:
31 divided by 878 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 878

Step 3:
314 divided by 878 is 0 with a remainder of 314.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 314, we end up with 314.
Take the next digit (3) from the dividend and append it to 314, then repeat: 3143 / 878

Advancing to step 4:
878 can be fit into 3143 3 times, resulting in a remainder of 509.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 509 after subtracting 2634 from 3143.
Grab the next digit (3) from the dividend, add it to 509, then carry on: 5093 / 878

Moving on to step 5:
The number 878 fits into 5093 5 times, leaving a remainder of 703.
Write down 5 as next digit of the result. 
Result so far: 35.0
Deduct 4390 from 5093 and we're left with 703.
Fetch the next digit (5) from the dividend, attach it to 703 and continue: 7035 / 878

Advancing to step 6:
7035 divided by 878 is 8 with a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 358.0
If we take 7024 away from 7035, we end up with 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 878

Let's proceed to step 7:
118 divided by 878 is 0 with a remainder of 118.
Use 0 as the next digit of our solution. 
Result so far: 3580.0
The remainder is 118 after subtracting 0 from 118.
Take the next digit (9) from the dividend and append it to 118, then repeat: 1189 / 878

Let's proceed to step 8:
The number 878 fits into 1189 1 times, leaving a remainder of 311.
Put 1 as the next digit of the answer. 
Result so far: 35801.0
Subtracting 878 from 1189 leaves us with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

On to step 9:
When dividing 3110 by 878, we get 3 with a remainder of 476.
The next digit of our result is 3. 
Result so far: 35801.3
The remainder is 476 after subtracting 2634 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 10:
4760 divided by 878 is 5 with a remainder of 370.
Use 5 as the next digit of our solution. 
Result so far: 35801.35
Subtracting 4390 from 4760 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 11:
878 can be fit into 3700 4 times, resulting in a remainder of 188.
Put 4 as the next digit of the answer. 
Result so far: 35801.354
Deduct 3512 from 3700 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 12:
The number 878 fits into 1880 2 times, leaving a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 35801.3542
Deduct 1756 from 1880 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 13:
878 can be fit into 1240 1 times, resulting in a remainder of 362.
The next digit of our result is 1. 
Result so far: 35801.35421
Subtract 878 from 1240 to get 362.
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 14:
If we divide 3620 by 878, we get 4 and a remainder of 108.
Use 4 as the next digit of our solution. 
Result so far: 35801.354214
Deduct 3512 from 3620 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 15:
If we divide 1080 by 878, we get 1 and a remainder of 202.
The next digit of our result is 1. 
Result so far: 35801.3542141
If we subtract 878 from 1080, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 16:
878 goes into 2020 2 times with a remainder of 264.
Write down 2 as next digit of the result. 
Result so far: 35801.35421412
If we take 1756 away from 2020, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

After the division, we end up with 35801.35421412 and a remainder of 2.64e-07.
