We're dividing 8356721 by 801 
We're looking to find how many times 801 goes into 8356721.

On to step 1:
801 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 801

On to step 2:
801 can be fit into 83 0 times, resulting in a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Append the next digit (5) from the dividend to 83 and continue with: 835 / 801

On to step 3:
When dividing 835 by 801, we get 1 with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 801 from 835 to get 34.
Append the next digit (6) from the dividend to 34 and continue with: 346 / 801

Moving on to step 4:
The number 801 fits into 346 0 times, leaving a remainder of 346.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 346 leaves us with 346.
Grab the next digit (7) from the dividend, add it to 346, then carry on: 3467 / 801

Going ahead to step 5:
The number 801 fits into 3467 4 times, leaving a remainder of 263.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Deduct 3204 from 3467 and we're left with 263.
Fetch the next digit (2) from the dividend, attach it to 263 and continue: 2632 / 801

On to step 6:
The number 801 fits into 2632 3 times, leaving a remainder of 229.
Write down 3 as next digit of the result. 
Result so far: 1043.0
Subtracting 2403 from 2632 leaves us with 229.
Take the next digit (1) from the dividend and append it to 229, then repeat: 2291 / 801

Step 7:
2291 divided by 801 is 2 with a remainder of 689.
Use 2 as the next digit of our solution. 
Result so far: 10432.0
If we subtract 1602 from 2291, we get 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Going ahead to step 8:
801 goes into 6890 8 times with a remainder of 482.
Write down 8 as next digit of the result. 
Result so far: 10432.8
Subtracting 6408 from 6890 leaves us with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Going ahead to step 9:
801 goes into 4820 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 10432.86
The remainder is 14 after subtracting 4806 from 4820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
801 goes into 140 0 times with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 10432.86
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
801 can be fit into 1400 1 times, resulting in a remainder of 599.
The next digit of our result is 1. 
Result so far: 10432.8601
If we subtract 801 from 1400, we get 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Step 12:
801 can be fit into 5990 7 times, resulting in a remainder of 383.
The number 7 becomes the next digit in our result. 
Result so far: 10432.86017
Subtracting 5607 from 5990 leaves us with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Moving on to step 13:
801 goes into 3830 4 times with a remainder of 626.
Put 4 as the next digit of the answer. 
Result so far: 10432.860174
Deduct 3204 from 3830 and we're left with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Moving on to step 14:
If we divide 6260 by 801, we get 7 and a remainder of 653.
The number 7 becomes the next digit in our result. 
Result so far: 10432.8601747
The remainder is 653 after subtracting 5607 from 6260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Moving on to step 15:
If we divide 6530 by 801, we get 8 and a remainder of 122.
The number 8 becomes the next digit in our result. 
Result so far: 10432.86017478
Subtracting 6408 from 6530 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

The final result is 10432.86017478 with a remainder of 1.22e-07.
