We're dividing 61899129 by 853 
Our goal is to divide 61899129 by 853.

Let's proceed to step 1:
The number 853 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 853

Let's proceed to step 2:
When dividing 61 by 853, we get 0 with a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 853

On to step 3:
853 can be fit into 618 0 times, resulting in a remainder of 618.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 618 and we're left with 618.
Take the next digit (9) from the dividend and append it to 618, then repeat: 6189 / 853

Step 4:
853 goes into 6189 7 times with a remainder of 218.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 5971 away from 6189, we end up with 218.
Append the next digit (9) from the dividend to 218 and continue with: 2189 / 853

Moving on to step 5:
If we divide 2189 by 853, we get 2 and a remainder of 483.
Write down 2 as next digit of the result. 
Result so far: 72.0
Deduct 1706 from 2189 and we're left with 483.
Append the next digit (1) from the dividend to 483 and continue with: 4831 / 853

Advancing to step 6:
4831 divided by 853 is 5 with a remainder of 566.
Put 5 as the next digit of the answer. 
Result so far: 725.0
Subtract 4265 from 4831 to get 566.
Append the next digit (2) from the dividend to 566 and continue with: 5662 / 853

Going ahead to step 7:
853 goes into 5662 6 times with a remainder of 544.
Put 6 as the next digit of the answer. 
Result so far: 7256.0
The remainder is 544 after subtracting 5118 from 5662.
Grab the next digit (9) from the dividend, add it to 544, then carry on: 5449 / 853

Let's proceed to step 8:
853 can be fit into 5449 6 times, resulting in a remainder of 331.
Put 6 as the next digit of the answer. 
Result so far: 72566.0
If we take 5118 away from 5449, we end up with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 9:
When dividing 3310 by 853, we get 3 with a remainder of 751.
The number 3 becomes the next digit in our result. 
Result so far: 72566.3
Subtracting 2559 from 3310 leaves us with 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7510, and continue the process.

Going ahead to step 10:
853 can be fit into 7510 8 times, resulting in a remainder of 686.
Record the quotient 8 as the next digit in the result. 
Result so far: 72566.38
If we take 6824 away from 7510, we end up with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Going ahead to step 11:
853 goes into 6860 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 72566.388
If we subtract 6824 from 6860, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 72566.388 and a remainder of 0.0036.
