891452 ÷ 31 
We want to figure out the number of times 891452 can be divided by 31.

Step 1:
The number 31 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 31

Step 2:
If we divide 89 by 31, we get 2 and a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 62 from 89 to get 27.
Take the next digit (1) from the dividend and append it to 27, then repeat: 271 / 31

Going ahead to step 3:
271 divided by 31 is 8 with a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we subtract 248 from 271, we get 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 31

Step 4:
The number 31 fits into 234 7 times, leaving a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 287.0
If we take 217 away from 234, we end up with 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 31

Advancing to step 5:
31 goes into 175 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 2875.0
If we take 155 away from 175, we end up with 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 31

Advancing to step 6:
If we divide 202 by 31, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 28756.0
If we take 186 away from 202, we end up 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.

Going ahead to step 7:
31 can be fit into 160 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 28756.5
If we subtract 155 from 160, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
31 goes into 50 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 28756.51
Subtract 31 from 50 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.

Step 9:
190 divided by 31 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 28756.516
The remainder is 4 after subtracting 186 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
The number 31 fits into 40 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 28756.5161
Deduct 31 from 40 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 11:
31 goes into 90 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 28756.51612
If we take 62 away from 90, we end up 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.

On to step 12:
When dividing 280 by 31, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 28756.516129
The remainder is 1 after subtracting 279 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 13:
31 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 28756.516129
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
31 goes into 100 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 28756.51612903
Deduct 93 from 100 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 28756.51612903 with a balance of 7e-09.
