74415693 ÷ 858 
Our goal is to divide 74415693 by 858.

Let's proceed to step 1:
858 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 858

Going ahead to step 2:
The number 858 fits into 74 0 times, leaving a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Append the next digit (4) from the dividend to 74 and continue with: 744 / 858

Let's proceed to step 3:
When dividing 744 by 858, we get 0 with a remainder of 744.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 744, we get 744.
Fetch the next digit (1) from the dividend, attach it to 744 and continue: 7441 / 858

Moving on to step 4:
The number 858 fits into 7441 8 times, leaving a remainder of 577.
The next digit of our result is 8. 
Result so far: 8.0
If we take 6864 away from 7441, we end up with 577.
Take the next digit (5) from the dividend and append it to 577, then repeat: 5775 / 858

Moving on to step 5:
When dividing 5775 by 858, we get 6 with a remainder of 627.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
If we subtract 5148 from 5775, we get 627.
Take the next digit (6) from the dividend and append it to 627, then repeat: 6276 / 858

Step 6:
858 can be fit into 6276 7 times, resulting in a remainder of 270.
Write down 7 as next digit of the result. 
Result so far: 867.0
Subtracting 6006 from 6276 leaves us with 270.
Include the next digit (9) from the dividend after 270, then repeat: 2709 / 858

Step 7:
When dividing 2709 by 858, we get 3 with a remainder of 135.
The number 3 becomes the next digit in our result. 
Result so far: 8673.0
The remainder is 135 after subtracting 2574 from 2709.
Grab the next digit (3) from the dividend, add it to 135, then carry on: 1353 / 858

Step 8:
If we divide 1353 by 858, we get 1 and a remainder of 495.
Write down 1 as next digit of the result. 
Result so far: 86731.0
If we take 858 away from 1353, we end up with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Moving on to step 9:
858 can be fit into 4950 5 times, resulting in a remainder of 660.
Record the quotient 5 as the next digit in the result. 
Result so far: 86731.5
If we subtract 4290 from 4950, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 10:
When dividing 6600 by 858, we get 7 with a remainder of 594.
Record the quotient 7 as the next digit in the result. 
Result so far: 86731.57
Deduct 6006 from 6600 and we're left with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Advancing to step 11:
The number 858 fits into 5940 6 times, leaving a remainder of 792.
Record the quotient 6 as the next digit in the result. 
Result so far: 86731.576
The remainder is 792 after subtracting 5148 from 5940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7920, and continue the process.

Advancing to step 12:
The number 858 fits into 7920 9 times, leaving a remainder of 198.
Record the quotient 9 as the next digit in the result. 
Result so far: 86731.5769
Subtracting 7722 from 7920 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 13:
858 goes into 1980 2 times with a remainder of 264.
Record the quotient 2 as the next digit in the result. 
Result so far: 86731.57692
Deduct 1716 from 1980 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 14:
858 goes into 2640 3 times with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 86731.576923
Subtract 2574 from 2640 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 15:
858 can be fit into 660 0 times, resulting in a remainder of 660.
Use 0 as the next digit of our solution. 
Result so far: 86731.576923
The remainder is 660 after subtracting 0 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 16:
858 goes into 6600 7 times with a remainder of 594.
Put 7 as the next digit of the answer. 
Result so far: 86731.57692307
If we subtract 6006 from 6600, we get 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

The final result is 86731.57692307 with a remainder of 5.94e-07.
