84645040 divided by 974 
Let's see how many times 974 fits into 84645040.

On to step 1:
974 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 974

Let's proceed to step 2:
974 can be fit into 84 0 times, resulting in a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Append the next digit (6) from the dividend to 84 and continue with: 846 / 974

On to step 3:
If we divide 846 by 974, we get 0 and a remainder of 846.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 846, we end up with 846.
Fetch the next digit (4) from the dividend, attach it to 846 and continue: 8464 / 974

Advancing to step 4:
974 goes into 8464 8 times with a remainder of 672.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 7792 from 8464 to get 672.
Include the next digit (5) from the dividend after 672, then repeat: 6725 / 974

Step 5:
If we divide 6725 by 974, we get 6 and a remainder of 881.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Deduct 5844 from 6725 and we're left with 881.
Append the next digit (0) from the dividend to 881 and continue with: 8810 / 974

Step 6:
974 can be fit into 8810 9 times, resulting in a remainder of 44.
The next digit of our result is 9. 
Result so far: 869.0
If we take 8766 away from 8810, we end up with 44.
Include the next digit (4) from the dividend after 44, then repeat: 444 / 974

Advancing to step 7:
If we divide 444 by 974, we get 0 and a remainder of 444.
Write down 0 as next digit of the result. 
Result so far: 8690.0
Subtracting 0 from 444 leaves us with 444.
Append the next digit (0) from the dividend to 444 and continue with: 4440 / 974

Let's proceed to step 8:
974 can be fit into 4440 4 times, resulting in a remainder of 544.
Record the quotient 4 as the next digit in the result. 
Result so far: 86904.0
Subtract 3896 from 4440 to 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.

Advancing to step 9:
974 can be fit into 5440 5 times, resulting in a remainder of 570.
The number 5 becomes the next digit in our result. 
Result so far: 86904.5
Deduct 4870 from 5440 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 10:
974 goes into 5700 5 times with a remainder of 830.
Record the quotient 5 as the next digit in the result. 
Result so far: 86904.55
Deduct 4870 from 5700 and we're left with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

In conclusion, the division gives 86904.55 with a balance of 0.83.
