We're dividing 870386 by 46 
We want to figure out the number of times 870386 can be divided by 46.

Advancing to step 1:
The number 46 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 46

Going ahead to step 2:
87 divided by 46 is 1 with a remainder of 41.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 46 from 87 and we're left with 41.
Include the next digit (0) from the dividend after 41, then repeat: 410 / 46

Moving on to step 3:
When dividing 410 by 46, we get 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 368 away from 410, we end up with 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 46

Let's proceed to step 4:
When dividing 423 by 46, we get 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 189.0
If we subtract 414 from 423, we get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 46

On to step 5:
98 divided by 46 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 1892.0
Deduct 92 from 98 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 46

Going ahead to step 6:
If we divide 66 by 46, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 18921.0
The remainder is 20 after subtracting 46 from 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
46 can be fit into 200 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 18921.4
If we take 184 away from 200, 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.

On to step 8:
If we divide 160 by 46, we get 3 and a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 18921.43
Deduct 138 from 160 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
When dividing 220 by 46, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 18921.434
If we take 184 away from 220, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
46 can be fit into 360 7 times, resulting in a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 18921.4347
Subtract 322 from 360 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
If we divide 380 by 46, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 18921.43478
If we take 368 away from 380, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
When dividing 120 by 46, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 18921.434782
The remainder is 28 after subtracting 92 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
If we divide 280 by 46, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 18921.4347826
Deduct 276 from 280 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
The number 46 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 18921.4347826
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 18921.4347826 with a balance of 4e-08.
