Let's divide 10920101 by 857
Our goal is to divide 10920101 by 857.

Advancing to step 1:
If we divide 1 by 857, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 857

Step 2:
If we divide 10 by 857, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 857

Let's proceed to step 3:
109 divided by 857 is 0 with a remainder of 109.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 109 after subtracting 0 from 109.
Append the next digit (2) from the dividend to 109 and continue with: 1092 / 857

Advancing to step 4:
When dividing 1092 by 857, we get 1 with a remainder of 235.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 857 from 1092 leaves us with 235.
Take the next digit (0) from the dividend and append it to 235, then repeat: 2350 / 857

On to step 5:
2350 divided by 857 is 2 with a remainder of 636.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 1714 from 2350 and we're left with 636.
Bring next digit (1) of the dividend behind the 636 and repeat the process: 6361 / 857

Let's proceed to step 6:
6361 divided by 857 is 7 with a remainder of 362.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
If we subtract 5999 from 6361, we get 362.
Bring next digit (0) of the dividend behind the 362 and repeat the process: 3620 / 857

Going ahead to step 7:
When dividing 3620 by 857, we get 4 with a remainder of 192.
The next digit of our result is 4. 
Result so far: 1274.0
If we take 3428 away from 3620, we end up with 192.
Include the next digit (1) from the dividend after 192, then repeat: 1921 / 857

Advancing to step 8:
857 goes into 1921 2 times with a remainder of 207.
The next digit of our result is 2. 
Result so far: 12742.0
The remainder is 207 after subtracting 1714 from 1921.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 9:
The number 857 fits into 2070 2 times, leaving a remainder of 356.
Record the quotient 2 as the next digit in the result. 
Result so far: 12742.2
Deduct 1714 from 2070 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 10:
857 goes into 3560 4 times with a remainder of 132.
Use 4 as the next digit of our solution. 
Result so far: 12742.24
If we take 3428 away from 3560, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 11:
If we divide 1320 by 857, we get 1 and a remainder of 463.
The next digit of our result is 1. 
Result so far: 12742.241
Subtract 857 from 1320 to get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Step 12:
857 can be fit into 4630 5 times, resulting in a remainder of 345.
Record the quotient 5 as the next digit in the result. 
Result so far: 12742.2415
Subtracting 4285 from 4630 leaves us with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 13:
857 goes into 3450 4 times with a remainder of 22.
The next digit of our result is 4. 
Result so far: 12742.24154
Deduct 3428 from 3450 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
When dividing 220 by 857, we get 0 with a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 12742.24154
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 15:
857 goes into 2200 2 times with a remainder of 486.
Write down 2 as next digit of the result. 
Result so far: 12742.2415402
Subtract 1714 from 2200 to get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Let's proceed to step 16:
4860 divided by 857 is 5 with a remainder of 575.
The next digit of our result is 5. 
Result so far: 12742.24154025
Subtract 4285 from 4860 to get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

The final outcome is 12742.24154025, with a leftover of 5.75e-07.
