36401381 divided by 851 
We want to figure out the number of times 36401381 can be divided by 851.

On to step 1:
When dividing 3 by 851, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 851

Advancing to step 2:
851 can be fit into 36 0 times, resulting in a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 851

On to step 3:
851 can be fit into 364 0 times, resulting in a remainder of 364.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 364 and we're left with 364.
Bring next digit (0) of the dividend behind the 364 and repeat the process: 3640 / 851

Going ahead to step 4:
3640 divided by 851 is 4 with a remainder of 236.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3404 away from 3640, we end up with 236.
Fetch the next digit (1) from the dividend, attach it to 236 and continue: 2361 / 851

Step 5:
851 goes into 2361 2 times with a remainder of 659.
The next digit of our result is 2. 
Result so far: 42.0
Subtract 1702 from 2361 to get 659.
Include the next digit (3) from the dividend after 659, then repeat: 6593 / 851

Advancing to step 6:
When dividing 6593 by 851, we get 7 with a remainder of 636.
The number 7 becomes the next digit in our result. 
Result so far: 427.0
Subtracting 5957 from 6593 leaves us with 636.
Bring next digit (8) of the dividend behind the 636 and repeat the process: 6368 / 851

Step 7:
6368 divided by 851 is 7 with a remainder of 411.
Write down 7 as next digit of the result. 
Result so far: 4277.0
The remainder is 411 after subtracting 5957 from 6368.
Grab the next digit (1) from the dividend, add it to 411, then carry on: 4111 / 851

Step 8:
851 goes into 4111 4 times with a remainder of 707.
The next digit of our result is 4. 
Result so far: 42774.0
Subtracting 3404 from 4111 leaves us with 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7070, and continue the process.

Let's proceed to step 9:
The number 851 fits into 7070 8 times, leaving a remainder of 262.
The number 8 becomes the next digit in our result. 
Result so far: 42774.8
The remainder is 262 after subtracting 6808 from 7070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 10:
851 goes into 2620 3 times with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 42774.83
The remainder is 67 after subtracting 2553 from 2620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 11:
851 can be fit into 670 0 times, resulting in a remainder of 670.
The next digit of our result is 0. 
Result so far: 42774.83
Subtracting 0 from 670 leaves us with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Going ahead to step 12:
If we divide 6700 by 851, we get 7 and a remainder of 743.
Write down 7 as next digit of the result. 
Result so far: 42774.8307
If we subtract 5957 from 6700, we get 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

On to step 13:
851 can be fit into 7430 8 times, resulting in a remainder of 622.
Write down 8 as next digit of the result. 
Result so far: 42774.83078
If we take 6808 away from 7430, we end up with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Going ahead to step 14:
851 can be fit into 6220 7 times, resulting in a remainder of 263.
Record the quotient 7 as the next digit in the result. 
Result so far: 42774.830787
Deduct 5957 from 6220 and we're left with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 15:
2630 divided by 851 is 3 with a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 42774.8307873
If we take 2553 away from 2630, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 16:
The number 851 fits into 770 0 times, leaving a remainder of 770.
Put 0 as the next digit of the answer. 
Result so far: 42774.8307873
Deduct 0 from 770 and we're left with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

After the division, we end up with 42774.8307873 and a remainder of 7.7e-07.
