We look at the division of 51676148 by 858 
We want to figure out the number of times 51676148 can be divided by 858.

Moving on to step 1:
The number 858 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 858

Step 2:
If we divide 51 by 858, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 858

Moving on to step 3:
516 divided by 858 is 0 with a remainder of 516.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 516 to get 516.
Bring next digit (7) of the dividend behind the 516 and repeat the process: 5167 / 858

Let's proceed to step 4:
When dividing 5167 by 858, we get 6 with a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 5148 from 5167 to get 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 858

Advancing to step 5:
858 can be fit into 196 0 times, resulting in a remainder of 196.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
The remainder is 196 after subtracting 0 from 196.
Bring next digit (1) of the dividend behind the 196 and repeat the process: 1961 / 858

Moving on to step 6:
1961 divided by 858 is 2 with a remainder of 245.
Record the quotient 2 as the next digit in the result. 
Result so far: 602.0
If we take 1716 away from 1961, we end up with 245.
Append the next digit (4) from the dividend to 245 and continue with: 2454 / 858

Let's proceed to step 7:
If we divide 2454 by 858, we get 2 and a remainder of 738.
Put 2 as the next digit of the answer. 
Result so far: 6022.0
Subtracting 1716 from 2454 leaves us with 738.
Bring next digit (8) of the dividend behind the 738 and repeat the process: 7388 / 858

Step 8:
When dividing 7388 by 858, we get 8 with a remainder of 524.
Record the quotient 8 as the next digit in the result. 
Result so far: 60228.0
Deduct 6864 from 7388 and we're left with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Step 9:
858 can be fit into 5240 6 times, resulting in a remainder of 92.
The next digit of our result is 6. 
Result so far: 60228.6
Deduct 5148 from 5240 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 10:
858 goes into 920 1 times with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 60228.61
The remainder is 62 after subtracting 858 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
The number 858 fits into 620 0 times, leaving a remainder of 620.
Put 0 as the next digit of the answer. 
Result so far: 60228.61
If we subtract 0 from 620, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 12:
The number 858 fits into 6200 7 times, leaving a remainder of 194.
Record the quotient 7 as the next digit in the result. 
Result so far: 60228.6107
Subtract 6006 from 6200 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 13:
If we divide 1940 by 858, we get 2 and a remainder of 224.
Use 2 as the next digit of our solution. 
Result so far: 60228.61072
Subtracting 1716 from 1940 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 14:
The number 858 fits into 2240 2 times, leaving a remainder of 524.
Record the quotient 2 as the next digit in the result. 
Result so far: 60228.610722
If we subtract 1716 from 2240, we get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

The final outcome is 60228.610722, with a leftover of 5.24e-05.
