We're dividing 858436 by 49 
Our goal is to divide 858436 by 49.

Moving on to step 1:
When dividing 8 by 49, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 49

Advancing to step 2:
The number 49 fits into 85 1 times, leaving a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 49 from 85 and we're left with 36.
Take the next digit (8) from the dividend and append it to 36, then repeat: 368 / 49

On to step 3:
49 goes into 368 7 times with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 343 from 368 and we're left with 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 49

Step 4:
The number 49 fits into 254 5 times, leaving a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 175.0
Subtract 245 from 254 to get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 49

Advancing to step 5:
The number 49 fits into 93 1 times, leaving a remainder of 44.
The next digit of our result is 1. 
Result so far: 1751.0
If we take 49 away from 93, we end up with 44.
Include the next digit (6) from the dividend after 44, then repeat: 446 / 49

On to step 6:
446 divided by 49 is 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 17519.0
If we subtract 441 from 446, 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.

Moving on to step 7:
If we divide 50 by 49, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 17519.1
Deduct 49 from 50 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
49 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 17519.1
Subtracting 0 from 10 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.

On to step 9:
49 goes into 100 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 17519.102
Subtract 98 from 100 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
The number 49 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 17519.102
Subtracting 0 from 20 leaves us with 20.
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 11:
The number 49 fits into 200 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 17519.10204
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
If we divide 40 by 49, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 17519.10204
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
When dividing 400 by 49, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 17519.1020408
Deduct 392 from 400 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.

Advancing to step 14:
80 divided by 49 is 1 with a remainder of 31.
The next digit of our result is 1. 
Result so far: 17519.10204081
If we take 49 away from 80, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 17519.10204081, with a leftover of 3.1e-08.
