We look at the division of 90970834 by 857 
Let's see how many times 857 fits into 90970834.

Let's proceed to step 1:
857 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 857

Going ahead to step 2:
The number 857 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Fetch the next digit (9) from the dividend, attach it to 90 and continue: 909 / 857

Step 3:
857 can be fit into 909 1 times, resulting in a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 857 from 909, we get 52.
Fetch the next digit (7) from the dividend, attach it to 52 and continue: 527 / 857

Moving on to step 4:
857 goes into 527 0 times with a remainder of 527.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 527 after subtracting 0 from 527.
Grab the next digit (0) from the dividend, add it to 527, then carry on: 5270 / 857

Moving on to step 5:
857 can be fit into 5270 6 times, resulting in a remainder of 128.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
Deduct 5142 from 5270 and we're left with 128.
Grab the next digit (8) from the dividend, add it to 128, then carry on: 1288 / 857

Going ahead to step 6:
The number 857 fits into 1288 1 times, leaving a remainder of 431.
Record the quotient 1 as the next digit in the result. 
Result so far: 1061.0
Deduct 857 from 1288 and we're left with 431.
Bring next digit (3) of the dividend behind the 431 and repeat the process: 4313 / 857

Going ahead to step 7:
If we divide 4313 by 857, we get 5 and a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 10615.0
If we take 4285 away from 4313, we end up with 28.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 857

Let's proceed to step 8:
284 divided by 857 is 0 with a remainder of 284.
The next digit of our result is 0. 
Result so far: 106150.0
If we take 0 away from 284, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 9:
2840 divided by 857 is 3 with a remainder of 269.
Write down 3 as next digit of the result. 
Result so far: 106150.3
Subtracting 2571 from 2840 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Advancing to step 10:
When dividing 2690 by 857, we get 3 with a remainder of 119.
The number 3 becomes the next digit in our result. 
Result so far: 106150.33
The remainder is 119 after subtracting 2571 from 2690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

After the division, we end up with 106150.33 and a remainder of 0.119.
