36443735 divided by 858 
We want to divide 36443735 by 858.

Going ahead to step 1:
When dividing 3 by 858, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 858

Going ahead to step 2:
858 goes into 36 0 times with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 858

Going ahead to step 3:
858 goes into 364 0 times with a remainder of 364.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 364 and we're left with 364.
Fetch the next digit (4) from the dividend, attach it to 364 and continue: 3644 / 858

On to step 4:
3644 divided by 858 is 4 with a remainder of 212.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 3432 from 3644 to get 212.
Grab the next digit (3) from the dividend, add it to 212, then carry on: 2123 / 858

Step 5:
If we divide 2123 by 858, we get 2 and a remainder of 407.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we take 1716 away from 2123, we end up with 407.
Bring next digit (7) of the dividend behind the 407 and repeat the process: 4077 / 858

Let's proceed to step 6:
858 goes into 4077 4 times with a remainder of 645.
The number 4 becomes the next digit in our result. 
Result so far: 424.0
Subtracting 3432 from 4077 leaves us with 645.
Bring next digit (3) of the dividend behind the 645 and repeat the process: 6453 / 858

Advancing to step 7:
If we divide 6453 by 858, we get 7 and a remainder of 447.
Use 7 as the next digit of our solution. 
Result so far: 4247.0
If we take 6006 away from 6453, we end up with 447.
Include the next digit (5) from the dividend after 447, then repeat: 4475 / 858

On to step 8:
When dividing 4475 by 858, we get 5 with a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 42475.0
Subtract 4290 from 4475 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 9:
858 can be fit into 1850 2 times, resulting in a remainder of 134.
The next digit of our result is 2. 
Result so far: 42475.2
Subtract 1716 from 1850 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 10:
If we divide 1340 by 858, we get 1 and a remainder of 482.
Use 1 as the next digit of our solution. 
Result so far: 42475.21
If we take 858 away from 1340, we end up 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.

Moving on to step 11:
858 goes into 4820 5 times with a remainder of 530.
Put 5 as the next digit of the answer. 
Result so far: 42475.215
If we subtract 4290 from 4820, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Moving on to step 12:
The number 858 fits into 5300 6 times, leaving a remainder of 152.
Use 6 as the next digit of our solution. 
Result so far: 42475.2156
Deduct 5148 from 5300 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 13:
When dividing 1520 by 858, we get 1 with a remainder of 662.
The number 1 becomes the next digit in our result. 
Result so far: 42475.21561
Deduct 858 from 1520 and we're left with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Going ahead to step 14:
858 goes into 6620 7 times with a remainder of 614.
Use 7 as the next digit of our solution. 
Result so far: 42475.215617
Subtracting 6006 from 6620 leaves us with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Let's proceed to step 15:
The number 858 fits into 6140 7 times, leaving a remainder of 134.
The next digit of our result is 7. 
Result so far: 42475.2156177
Subtracting 6006 from 6140 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

The final outcome is 42475.2156177, with a leftover of 1.34e-06.
