We look at the division of 16826521 by 846 
Our goal is to divide 16826521 by 846.

Going ahead to step 1:
1 divided by 846 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 846

Let's proceed to step 2:
If we divide 16 by 846, we get 0 and a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 846

On to step 3:
The number 846 fits into 168 0 times, leaving a remainder of 168.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 168 after subtracting 0 from 168.
Grab the next digit (2) from the dividend, add it to 168, then carry on: 1682 / 846

Step 4:
The number 846 fits into 1682 1 times, leaving a remainder of 836.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 846 from 1682 to get 836.
Fetch the next digit (6) from the dividend, attach it to 836 and continue: 8366 / 846

Advancing to step 5:
The number 846 fits into 8366 9 times, leaving a remainder of 752.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we take 7614 away from 8366, we end up with 752.
Bring next digit (5) of the dividend behind the 752 and repeat the process: 7525 / 846

Going ahead to step 6:
When dividing 7525 by 846, we get 8 with a remainder of 757.
The next digit of our result is 8. 
Result so far: 198.0
Deduct 6768 from 7525 and we're left with 757.
Append the next digit (2) from the dividend to 757 and continue with: 7572 / 846

Advancing to step 7:
The number 846 fits into 7572 8 times, leaving a remainder of 804.
Use 8 as the next digit of our solution. 
Result so far: 1988.0
Subtracting 6768 from 7572 leaves us with 804.
Take the next digit (1) from the dividend and append it to 804, then repeat: 8041 / 846

Going ahead to step 8:
When dividing 8041 by 846, we get 9 with a remainder of 427.
Use 9 as the next digit of our solution. 
Result so far: 19889.0
If we subtract 7614 from 8041, we get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Going ahead to step 9:
If we divide 4270 by 846, we get 5 and a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 19889.5
Deduct 4230 from 4270 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
When dividing 400 by 846, we get 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 19889.5
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 11:
846 goes into 4000 4 times with a remainder of 616.
Record the quotient 4 as the next digit in the result. 
Result so far: 19889.504
If we subtract 3384 from 4000, we get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Advancing to step 12:
6160 divided by 846 is 7 with a remainder of 238.
Put 7 as the next digit of the answer. 
Result so far: 19889.5047
Deduct 5922 from 6160 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 13:
846 can be fit into 2380 2 times, resulting in a remainder of 688.
Put 2 as the next digit of the answer. 
Result so far: 19889.50472
Subtract 1692 from 2380 to get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Advancing to step 14:
6880 divided by 846 is 8 with a remainder of 112.
The next digit of our result is 8. 
Result so far: 19889.504728
If we take 6768 away from 6880, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 15:
The number 846 fits into 1120 1 times, leaving a remainder of 274.
The number 1 becomes the next digit in our result. 
Result so far: 19889.5047281
Subtracting 846 from 1120 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 16:
If we divide 2740 by 846, we get 3 and a remainder of 202.
Write down 3 as next digit of the result. 
Result so far: 19889.50472813
If we take 2538 away from 2740, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

The final outcome is 19889.50472813, with a leftover of 2.02e-07.
