We look at the division of 74237978 by 859 
Our goal is to divide 74237978 by 859.

Let's proceed to step 1:
The number 859 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 859

Advancing to step 2:
If we divide 74 by 859, we get 0 and a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 859

Step 3:
859 goes into 742 0 times with a remainder of 742.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 742 leaves us with 742.
Take the next digit (3) from the dividend and append it to 742, then repeat: 7423 / 859

Let's proceed to step 4:
The number 859 fits into 7423 8 times, leaving a remainder of 551.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 6872 from 7423 and we're left with 551.
Grab the next digit (7) from the dividend, add it to 551, then carry on: 5517 / 859

On to step 5:
5517 divided by 859 is 6 with a remainder of 363.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we subtract 5154 from 5517, we get 363.
Grab the next digit (9) from the dividend, add it to 363, then carry on: 3639 / 859

Let's proceed to step 6:
859 goes into 3639 4 times with a remainder of 203.
The next digit of our result is 4. 
Result so far: 864.0
If we take 3436 away from 3639, we end up with 203.
Bring next digit (7) of the dividend behind the 203 and repeat the process: 2037 / 859

Let's proceed to step 7:
The number 859 fits into 2037 2 times, leaving a remainder of 319.
Write down 2 as next digit of the result. 
Result so far: 8642.0
Subtracting 1718 from 2037 leaves us with 319.
Append the next digit (8) from the dividend to 319 and continue with: 3198 / 859

Going ahead to step 8:
When dividing 3198 by 859, we get 3 with a remainder of 621.
Write down 3 as next digit of the result. 
Result so far: 86423.0
Subtracting 2577 from 3198 leaves us with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

On to step 9:
859 can be fit into 6210 7 times, resulting in a remainder of 197.
Write down 7 as next digit of the result. 
Result so far: 86423.7
Deduct 6013 from 6210 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 10:
1970 divided by 859 is 2 with a remainder of 252.
The number 2 becomes the next digit in our result. 
Result so far: 86423.72
The remainder is 252 after subtracting 1718 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 11:
859 goes into 2520 2 times with a remainder of 802.
Write down 2 as next digit of the result. 
Result so far: 86423.722
Subtract 1718 from 2520 to get 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

After the division, we end up with 86423.722 and a remainder of 0.0802.
