Let's divide 78474303 by 858
We want to divide 78474303 by 858.

Let's proceed to step 1:
When dividing 7 by 858, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 858

Let's proceed to step 2:
If we divide 78 by 858, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (4) from the dividend and append it to 78, then repeat: 784 / 858

Advancing to step 3:
784 divided by 858 is 0 with a remainder of 784.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 784 to get 784.
Grab the next digit (7) from the dividend, add it to 784, then carry on: 7847 / 858

Moving on to step 4:
The number 858 fits into 7847 9 times, leaving a remainder of 125.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 125 after subtracting 7722 from 7847.
Include the next digit (4) from the dividend after 125, then repeat: 1254 / 858

Moving on to step 5:
The number 858 fits into 1254 1 times, leaving a remainder of 396.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
If we subtract 858 from 1254, we get 396.
Bring next digit (3) of the dividend behind the 396 and repeat the process: 3963 / 858

Advancing to step 6:
If we divide 3963 by 858, we get 4 and a remainder of 531.
Use 4 as the next digit of our solution. 
Result so far: 914.0
Subtracting 3432 from 3963 leaves us with 531.
Take the next digit (0) from the dividend and append it to 531, then repeat: 5310 / 858

Let's proceed to step 7:
858 can be fit into 5310 6 times, resulting in a remainder of 162.
The next digit of our result is 6. 
Result so far: 9146.0
Subtract 5148 from 5310 to get 162.
Grab the next digit (3) from the dividend, add it to 162, then carry on: 1623 / 858

Moving on to step 8:
If we divide 1623 by 858, we get 1 and a remainder of 765.
Record the quotient 1 as the next digit in the result. 
Result so far: 91461.0
If we take 858 away from 1623, we end up with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

On to step 9:
858 goes into 7650 8 times with a remainder of 786.
Use 8 as the next digit of our solution. 
Result so far: 91461.8
Subtract 6864 from 7650 to get 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

Going ahead to step 10:
If we divide 7860 by 858, we get 9 and a remainder of 138.
Use 9 as the next digit of our solution. 
Result so far: 91461.89
Deduct 7722 from 7860 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Step 11:
If we divide 1380 by 858, we get 1 and a remainder of 522.
Write down 1 as next digit of the result. 
Result so far: 91461.891
Subtract 858 from 1380 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Step 12:
858 goes into 5220 6 times with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 91461.8916
Subtract 5148 from 5220 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
720 divided by 858 is 0 with a remainder of 720.
Use 0 as the next digit of our solution. 
Result so far: 91461.8916
If we subtract 0 from 720, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 14:
The number 858 fits into 7200 8 times, leaving a remainder of 336.
The number 8 becomes the next digit in our result. 
Result so far: 91461.891608
Subtracting 6864 from 7200 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 15:
When dividing 3360 by 858, we get 3 with a remainder of 786.
The number 3 becomes the next digit in our result. 
Result so far: 91461.8916083
If we take 2574 away from 3360, we end up with 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

Let's proceed to step 16:
If we divide 7860 by 858, we get 9 and a remainder of 138.
The next digit of our result is 9. 
Result so far: 91461.89160839
Deduct 7722 from 7860 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final result is 91461.89160839 with a remainder of 1.38e-07.
