840657 ÷ 46 
We're looking to find how many times 46 goes into 840657.

Going ahead to step 1:
If we divide 8 by 46, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 46

Let's proceed to step 2:
84 divided by 46 is 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 46 from 84 leaves us with 38.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 46

Step 3:
380 divided by 46 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 368 away from 380, we end up with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 46

Advancing to step 4:
When dividing 126 by 46, we get 2 with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 182.0
The remainder is 34 after subtracting 92 from 126.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 46

On to step 5:
When dividing 345 by 46, we get 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 1827.0
If we take 322 away from 345, we end up with 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 46

Moving on to step 6:
46 can be fit into 237 5 times, resulting in a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 18275.0
Subtract 230 from 237 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
If we divide 70 by 46, we get 1 and a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 18275.1
If we subtract 46 from 70, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
46 goes into 240 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 18275.15
Subtracting 230 from 240 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
46 can be fit into 100 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 18275.152
Deduct 92 from 100 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
80 divided by 46 is 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 18275.1521
If we take 46 away from 80, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 11:
If we divide 340 by 46, we get 7 and a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 18275.15217
Deduct 322 from 340 and we're left with 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 12:
If we divide 180 by 46, we get 3 and a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 18275.152173
If we subtract 138 from 180, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
If we divide 420 by 46, we get 9 and a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 18275.1521739
The remainder is 6 after subtracting 414 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
The number 46 fits into 60 1 times, leaving a remainder of 14.
The next digit of our result is 1. 
Result so far: 18275.15217391
If we subtract 46 from 60, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 18275.15217391 with a remaining 1.4e-08.
