We look at the division of 86404127 by 846 
We're looking to find how many times 846 goes into 86404127.

On to step 1:
The number 846 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
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 846

Let's proceed to step 2:
846 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Take the next digit (4) from the dividend and append it to 86, then repeat: 864 / 846

Going ahead to step 3:
864 divided by 846 is 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 846 from 864 and we're left with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 846

Going ahead to step 4:
180 divided by 846 is 0 with a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 180, we end up with 180.
Grab the next digit (4) from the dividend, add it to 180, then carry on: 1804 / 846

Advancing to step 5:
The number 846 fits into 1804 2 times, leaving a remainder of 112.
Write down 2 as next digit of the result. 
Result so far: 102.0
If we take 1692 away from 1804, we end up with 112.
Bring next digit (1) of the dividend behind the 112 and repeat the process: 1121 / 846

On to step 6:
846 goes into 1121 1 times with a remainder of 275.
Record the quotient 1 as the next digit in the result. 
Result so far: 1021.0
If we take 846 away from 1121, we end up with 275.
Bring next digit (2) of the dividend behind the 275 and repeat the process: 2752 / 846

On to step 7:
846 can be fit into 2752 3 times, resulting in a remainder of 214.
The number 3 becomes the next digit in our result. 
Result so far: 10213.0
If we take 2538 away from 2752, we end up with 214.
Bring next digit (7) of the dividend behind the 214 and repeat the process: 2147 / 846

Let's proceed to step 8:
The number 846 fits into 2147 2 times, leaving a remainder of 455.
Use 2 as the next digit of our solution. 
Result so far: 102132.0
Deduct 1692 from 2147 and we're left with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Step 9:
The number 846 fits into 4550 5 times, leaving a remainder of 320.
Write down 5 as next digit of the result. 
Result so far: 102132.5
Subtract 4230 from 4550 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 10:
When dividing 3200 by 846, we get 3 with a remainder of 662.
The number 3 becomes the next digit in our result. 
Result so far: 102132.53
If we subtract 2538 from 3200, we get 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Going ahead to step 11:
6620 divided by 846 is 7 with a remainder of 698.
Write down 7 as next digit of the result. 
Result so far: 102132.537
The remainder is 698 after subtracting 5922 from 6620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

On to step 12:
6980 divided by 846 is 8 with a remainder of 212.
Put 8 as the next digit of the answer. 
Result so far: 102132.5378
Deduct 6768 from 6980 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 13:
The number 846 fits into 2120 2 times, leaving a remainder of 428.
Put 2 as the next digit of the answer. 
Result so far: 102132.53782
If we take 1692 away from 2120, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 14:
The number 846 fits into 4280 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 102132.537825
If we subtract 4230 from 4280, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 15:
If we divide 500 by 846, we get 0 and a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 102132.537825
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 16:
846 can be fit into 5000 5 times, resulting in a remainder of 770.
Write down 5 as next digit of the result. 
Result so far: 102132.53782505
Subtracting 4230 from 5000 leaves us with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

The final outcome is 102132.53782505, with a leftover of 7.7e-07.
