We're dividing 78813199 by 974 
Our goal is to divide 78813199 by 974.

Step 1:
974 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 974

Going ahead to step 2:
974 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Append the next digit (8) from the dividend to 78 and continue with: 788 / 974

Let's proceed to step 3:
When dividing 788 by 974, we get 0 with a remainder of 788.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 788 to get 788.
Include the next digit (1) from the dividend after 788, then repeat: 7881 / 974

Let's proceed to step 4:
7881 divided by 974 is 8 with a remainder of 89.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 7792 away from 7881, we end up with 89.
Bring next digit (3) of the dividend behind the 89 and repeat the process: 893 / 974

On to step 5:
974 goes into 893 0 times with a remainder of 893.
The next digit of our result is 0. 
Result so far: 80.0
If we subtract 0 from 893, we get 893.
Take the next digit (1) from the dividend and append it to 893, then repeat: 8931 / 974

Moving on to step 6:
When dividing 8931 by 974, we get 9 with a remainder of 165.
Record the quotient 9 as the next digit in the result. 
Result so far: 809.0
The remainder is 165 after subtracting 8766 from 8931.
Bring next digit (9) of the dividend behind the 165 and repeat the process: 1659 / 974

Step 7:
When dividing 1659 by 974, we get 1 with a remainder of 685.
The number 1 becomes the next digit in our result. 
Result so far: 8091.0
Deduct 974 from 1659 and we're left with 685.
Bring next digit (9) of the dividend behind the 685 and repeat the process: 6859 / 974

Going ahead to step 8:
974 goes into 6859 7 times with a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 80917.0
Deduct 6818 from 6859 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 9:
974 goes into 410 0 times with a remainder of 410.
Put 0 as the next digit of the answer. 
Result so far: 80917.0
Deduct 0 from 410 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 10:
4100 divided by 974 is 4 with a remainder of 204.
Record the quotient 4 as the next digit in the result. 
Result so far: 80917.04
Subtracting 3896 from 4100 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 11:
974 can be fit into 2040 2 times, resulting in a remainder of 92.
Use 2 as the next digit of our solution. 
Result so far: 80917.042
If we take 1948 away from 2040, we end up 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 12:
974 can be fit into 920 0 times, resulting in a remainder of 920.
The number 0 becomes the next digit in our result. 
Result so far: 80917.042
If we take 0 away from 920, we end up with 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9200, and continue the process.

Let's proceed to step 13:
974 can be fit into 9200 9 times, resulting in a remainder of 434.
Put 9 as the next digit of the answer. 
Result so far: 80917.04209
Subtracting 8766 from 9200 leaves us with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Advancing to step 14:
When dividing 4340 by 974, we get 4 with a remainder of 444.
Put 4 as the next digit of the answer. 
Result so far: 80917.042094
Subtract 3896 from 4340 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Going ahead to step 15:
974 can be fit into 4440 4 times, resulting in a remainder of 544.
Put 4 as the next digit of the answer. 
Result so far: 80917.0420944
If we subtract 3896 from 4440, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

The final outcome is 80917.0420944, with a leftover of 5.44e-06.
