Let's divide 86423523 by 906
We're looking to find how many times 906 goes into 86423523.

Moving on to step 1:
8 divided by 906 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 906

Going ahead to step 2:
906 goes into 86 0 times with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 906

Moving on to step 3:
864 divided by 906 is 0 with a remainder of 864.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 864 and we're left with 864.
Include the next digit (2) from the dividend after 864, then repeat: 8642 / 906

Step 4:
906 can be fit into 8642 9 times, resulting in a remainder of 488.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 8154 from 8642, we get 488.
Take the next digit (3) from the dividend and append it to 488, then repeat: 4883 / 906

Advancing to step 5:
When dividing 4883 by 906, we get 5 with a remainder of 353.
Put 5 as the next digit of the answer. 
Result so far: 95.0
The remainder is 353 after subtracting 4530 from 4883.
Bring next digit (5) of the dividend behind the 353 and repeat the process: 3535 / 906

On to step 6:
906 can be fit into 3535 3 times, resulting in a remainder of 817.
The number 3 becomes the next digit in our result. 
Result so far: 953.0
Subtract 2718 from 3535 to get 817.
Bring next digit (2) of the dividend behind the 817 and repeat the process: 8172 / 906

Advancing to step 7:
The number 906 fits into 8172 9 times, leaving a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 9539.0
The remainder is 18 after subtracting 8154 from 8172.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 906

Step 8:
If we divide 183 by 906, we get 0 and a remainder of 183.
Write down 0 as next digit of the result. 
Result so far: 95390.0
Subtract 0 from 183 to get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Moving on to step 9:
The number 906 fits into 1830 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 95390.2
If we subtract 1812 from 1830, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
If we divide 180 by 906, we get 0 and a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 95390.2
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
1800 divided by 906 is 1 with a remainder of 894.
The next digit of our result is 1. 
Result so far: 95390.201
Deduct 906 from 1800 and we're left with 894.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8940, and continue the process.

Step 12:
The number 906 fits into 8940 9 times, leaving a remainder of 786.
Put 9 as the next digit of the answer. 
Result so far: 95390.2019
If we take 8154 away from 8940, we end up with 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

On to step 13:
906 can be fit into 7860 8 times, resulting in a remainder of 612.
Put 8 as the next digit of the answer. 
Result so far: 95390.20198
If we subtract 7248 from 7860, we get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Going ahead to step 14:
If we divide 6120 by 906, we get 6 and a remainder of 684.
Write down 6 as next digit of the result. 
Result so far: 95390.201986
If we take 5436 away from 6120, we end up with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Advancing to step 15:
6840 divided by 906 is 7 with a remainder of 498.
Use 7 as the next digit of our solution. 
Result so far: 95390.2019867
Subtract 6342 from 6840 to get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Going ahead to step 16:
906 can be fit into 4980 5 times, resulting in a remainder of 450.
The next digit of our result is 5. 
Result so far: 95390.20198675
Subtracting 4530 from 4980 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Our division results in 95390.20198675 with a remaining 4.5e-07.
