Let's divide 46246786 by 858
We want to divide 46246786 by 858.

Step 1:
If we divide 4 by 858, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 858

Going ahead to step 2:
When dividing 46 by 858, we get 0 with a remainder of 46.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 46, we end up with 46.
Fetch the next digit (2) from the dividend, attach it to 46 and continue: 462 / 858

On to step 3:
If we divide 462 by 858, we get 0 and a remainder of 462.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 462 after subtracting 0 from 462.
Take the next digit (4) from the dividend and append it to 462, then repeat: 4624 / 858

Moving on to step 4:
The number 858 fits into 4624 5 times, leaving a remainder of 334.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 4290 from 4624 and we're left with 334.
Include the next digit (6) from the dividend after 334, then repeat: 3346 / 858

On to step 5:
3346 divided by 858 is 3 with a remainder of 772.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
If we take 2574 away from 3346, we end up with 772.
Include the next digit (7) from the dividend after 772, then repeat: 7727 / 858

Step 6:
When dividing 7727 by 858, we get 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 539.0
The remainder is 5 after subtracting 7722 from 7727.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 858

On to step 7:
858 goes into 58 0 times with a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 5390.0
Deduct 0 from 58 and we're left with 58.
Fetch the next digit (6) from the dividend, attach it to 58 and continue: 586 / 858

Let's proceed to step 8:
If we divide 586 by 858, we get 0 and a remainder of 586.
The next digit of our result is 0. 
Result so far: 53900.0
Subtracting 0 from 586 leaves us with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Moving on to step 9:
858 goes into 5860 6 times with a remainder of 712.
The next digit of our result is 6. 
Result so far: 53900.6
Subtract 5148 from 5860 to get 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Let's proceed to step 10:
The number 858 fits into 7120 8 times, leaving a remainder of 256.
Record the quotient 8 as the next digit in the result. 
Result so far: 53900.68
If we subtract 6864 from 7120, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 11:
The number 858 fits into 2560 2 times, leaving a remainder of 844.
The next digit of our result is 2. 
Result so far: 53900.682
Deduct 1716 from 2560 and we're left with 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

Let's proceed to step 12:
8440 divided by 858 is 9 with a remainder of 718.
Record the quotient 9 as the next digit in the result. 
Result so far: 53900.6829
The remainder is 718 after subtracting 7722 from 8440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Advancing to step 13:
When dividing 7180 by 858, we get 8 with a remainder of 316.
The number 8 becomes the next digit in our result. 
Result so far: 53900.68298
Subtract 6864 from 7180 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 14:
When dividing 3160 by 858, we get 3 with a remainder of 586.
Put 3 as the next digit of the answer. 
Result so far: 53900.682983
If we subtract 2574 from 3160, we get 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Advancing to step 15:
858 can be fit into 5860 6 times, resulting in a remainder of 712.
Write down 6 as next digit of the result. 
Result so far: 53900.6829836
If we subtract 5148 from 5860, we get 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

On to step 16:
If we divide 7120 by 858, we get 8 and a remainder of 256.
The next digit of our result is 8. 
Result so far: 53900.68298368
If we subtract 6864 from 7120, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The quotient of the division is 53900.68298368, and the remainder is 2.56e-07.
