99378425 divided by 857 
We want to divide 99378425 by 857.

On to step 1:
When dividing 9 by 857, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 857

Let's proceed to step 2:
If we divide 99 by 857, we get 0 and a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Include the next digit (3) from the dividend after 99, then repeat: 993 / 857

Moving on to step 3:
857 can be fit into 993 1 times, resulting in a remainder of 136.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 857 from 993 to get 136.
Grab the next digit (7) from the dividend, add it to 136, then carry on: 1367 / 857

Let's proceed to step 4:
857 can be fit into 1367 1 times, resulting in a remainder of 510.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 857 from 1367 and we're left with 510.
Fetch the next digit (8) from the dividend, attach it to 510 and continue: 5108 / 857

On to step 5:
5108 divided by 857 is 5 with a remainder of 823.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
If we take 4285 away from 5108, we end up with 823.
Take the next digit (4) from the dividend and append it to 823, then repeat: 8234 / 857

On to step 6:
857 can be fit into 8234 9 times, resulting in a remainder of 521.
The number 9 becomes the next digit in our result. 
Result so far: 1159.0
Subtracting 7713 from 8234 leaves us with 521.
Bring next digit (2) of the dividend behind the 521 and repeat the process: 5212 / 857

Let's proceed to step 7:
If we divide 5212 by 857, we get 6 and a remainder of 70.
Put 6 as the next digit of the answer. 
Result so far: 11596.0
Subtracting 5142 from 5212 leaves us with 70.
Include the next digit (5) from the dividend after 70, then repeat: 705 / 857

Moving on to step 8:
857 goes into 705 0 times with a remainder of 705.
Write down 0 as next digit of the result. 
Result so far: 115960.0
If we take 0 away from 705, we end up with 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Advancing to step 9:
The number 857 fits into 7050 8 times, leaving a remainder of 194.
Put 8 as the next digit of the answer. 
Result so far: 115960.8
Subtract 6856 from 7050 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 10:
857 goes into 1940 2 times with a remainder of 226.
The next digit of our result is 2. 
Result so far: 115960.82
Deduct 1714 from 1940 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 11:
If we divide 2260 by 857, we get 2 and a remainder of 546.
Write down 2 as next digit of the result. 
Result so far: 115960.822
If we take 1714 away from 2260, we end up with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

The quotient of the division is 115960.822, and the remainder is 0.0546.
