We look at the division of 96405143 by 858 
Our goal is to divide 96405143 by 858.

On to step 1:
If we divide 9 by 858, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 858

Going ahead to step 2:
858 goes into 96 0 times with a remainder of 96.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 96, we get 96.
Bring next digit (4) of the dividend behind the 96 and repeat the process: 964 / 858

Moving on to step 3:
When dividing 964 by 858, we get 1 with a remainder of 106.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 858 away from 964, we end up with 106.
Grab the next digit (0) from the dividend, add it to 106, then carry on: 1060 / 858

Moving on to step 4:
1060 divided by 858 is 1 with a remainder of 202.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 858 away from 1060, we end up with 202.
Grab the next digit (5) from the dividend, add it to 202, then carry on: 2025 / 858

Let's proceed to step 5:
858 goes into 2025 2 times with a remainder of 309.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
If we take 1716 away from 2025, we end up with 309.
Bring next digit (1) of the dividend behind the 309 and repeat the process: 3091 / 858

Advancing to step 6:
858 goes into 3091 3 times with a remainder of 517.
Use 3 as the next digit of our solution. 
Result so far: 1123.0
Subtracting 2574 from 3091 leaves us with 517.
Take the next digit (4) from the dividend and append it to 517, then repeat: 5174 / 858

Moving on to step 7:
858 goes into 5174 6 times with a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 11236.0
The remainder is 26 after subtracting 5148 from 5174.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 858

Step 8:
The number 858 fits into 263 0 times, leaving a remainder of 263.
Write down 0 as next digit of the result. 
Result so far: 112360.0
Subtract 0 from 263 to get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

On to step 9:
The number 858 fits into 2630 3 times, leaving a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 112360.3
Deduct 2574 from 2630 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
560 divided by 858 is 0 with a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 112360.3
Deduct 0 from 560 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 11:
When dividing 5600 by 858, we get 6 with a remainder of 452.
Put 6 as the next digit of the answer. 
Result so far: 112360.306
Subtract 5148 from 5600 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 12:
4520 divided by 858 is 5 with a remainder of 230.
Write down 5 as next digit of the result. 
Result so far: 112360.3065
Subtracting 4290 from 4520 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 13:
858 can be fit into 2300 2 times, resulting in a remainder of 584.
Use 2 as the next digit of our solution. 
Result so far: 112360.30652
Subtracting 1716 from 2300 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Let's proceed to step 14:
858 can be fit into 5840 6 times, resulting in a remainder of 692.
Put 6 as the next digit of the answer. 
Result so far: 112360.306526
If we subtract 5148 from 5840, we get 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Step 15:
858 can be fit into 6920 8 times, resulting in a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 112360.3065268
The remainder is 56 after subtracting 6864 from 6920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 16:
560 divided by 858 is 0 with a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 112360.3065268
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The final outcome is 112360.3065268, with a leftover of 5.6e-07.
