Let's divide 77850142 by 853
We want to figure out the number of times 77850142 can be divided by 853.

Moving on to step 1:
If we divide 7 by 853, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 853

Going ahead to step 2:
77 divided by 853 is 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Fetch the next digit (8) from the dividend, attach it to 77 and continue: 778 / 853

Advancing to step 3:
When dividing 778 by 853, we get 0 with a remainder of 778.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 778 and we're left with 778.
Append the next digit (5) from the dividend to 778 and continue with: 7785 / 853

Moving on to step 4:
If we divide 7785 by 853, we get 9 and a remainder of 108.
The next digit of our result is 9. 
Result so far: 9.0
If we take 7677 away from 7785, we end up with 108.
Grab the next digit (0) from the dividend, add it to 108, then carry on: 1080 / 853

Going ahead to step 5:
853 goes into 1080 1 times with a remainder of 227.
The next digit of our result is 1. 
Result so far: 91.0
The remainder is 227 after subtracting 853 from 1080.
Fetch the next digit (1) from the dividend, attach it to 227 and continue: 2271 / 853

Let's proceed to step 6:
2271 divided by 853 is 2 with a remainder of 565.
The next digit of our result is 2. 
Result so far: 912.0
Subtracting 1706 from 2271 leaves us with 565.
Take the next digit (4) from the dividend and append it to 565, then repeat: 5654 / 853

Moving on to step 7:
5654 divided by 853 is 6 with a remainder of 536.
Put 6 as the next digit of the answer. 
Result so far: 9126.0
If we subtract 5118 from 5654, we get 536.
Bring next digit (2) of the dividend behind the 536 and repeat the process: 5362 / 853

Let's proceed to step 8:
When dividing 5362 by 853, we get 6 with a remainder of 244.
The number 6 becomes the next digit in our result. 
Result so far: 91266.0
Subtract 5118 from 5362 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 9:
If we divide 2440 by 853, we get 2 and a remainder of 734.
Write down 2 as next digit of the result. 
Result so far: 91266.2
If we subtract 1706 from 2440, we get 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

Moving on to step 10:
The number 853 fits into 7340 8 times, leaving a remainder of 516.
Put 8 as the next digit of the answer. 
Result so far: 91266.28
Subtracting 6824 from 7340 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

On to step 11:
When dividing 5160 by 853, we get 6 with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 91266.286
The remainder is 42 after subtracting 5118 from 5160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
853 can be fit into 420 0 times, resulting in a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 91266.286
Deduct 0 from 420 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 13:
4200 divided by 853 is 4 with a remainder of 788.
Put 4 as the next digit of the answer. 
Result so far: 91266.28604
Subtracting 3412 from 4200 leaves us with 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Step 14:
7880 divided by 853 is 9 with a remainder of 203.
The number 9 becomes the next digit in our result. 
Result so far: 91266.286049
The remainder is 203 after subtracting 7677 from 7880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Step 15:
2030 divided by 853 is 2 with a remainder of 324.
Record the quotient 2 as the next digit in the result. 
Result so far: 91266.2860492
Deduct 1706 from 2030 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 16:
The number 853 fits into 3240 3 times, leaving a remainder of 681.
The number 3 becomes the next digit in our result. 
Result so far: 91266.28604923
Subtracting 2559 from 3240 leaves us with 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

The final result is 91266.28604923 with a remainder of 6.81e-07.
