We look at the division of 51534345 by 849 
We want to divide 51534345 by 849.

Step 1:
849 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 849

Moving on to step 2:
849 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 849

Advancing to step 3:
849 goes into 515 0 times with a remainder of 515.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 515, we get 515.
Append the next digit (3) from the dividend to 515 and continue with: 5153 / 849

Moving on to step 4:
The number 849 fits into 5153 6 times, leaving a remainder of 59.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 5094 away from 5153, we end up with 59.
Take the next digit (4) from the dividend and append it to 59, then repeat: 594 / 849

Advancing to step 5:
The number 849 fits into 594 0 times, leaving a remainder of 594.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
If we subtract 0 from 594, we get 594.
Append the next digit (3) from the dividend to 594 and continue with: 5943 / 849

Moving on to step 6:
The number 849 fits into 5943 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 607.0
Subtract 5943 from 5943 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 849

Going ahead to step 7:
849 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 6070.0
If we take 0 away from 4, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 849

Going ahead to step 8:
849 can be fit into 45 0 times, resulting in a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 60700.0
Deduct 0 from 45 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 9:
The number 849 fits into 450 0 times, leaving a remainder of 450.
The number 0 becomes the next digit in our result. 
Result so far: 60700.0
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 10:
849 can be fit into 4500 5 times, resulting in a remainder of 255.
The next digit of our result is 5. 
Result so far: 60700.05
If we subtract 4245 from 4500, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 11:
849 can be fit into 2550 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 60700.053
If we take 2547 away from 2550, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
849 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 60700.053
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
849 can be fit into 300 0 times, resulting in a remainder of 300.
The next digit of our result is 0. 
Result so far: 60700.053
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 60700.053 with a remaining 0.0003.
