Let's divide 15505550 by 974
We're looking to find how many times 974 goes into 15505550.

Moving on to step 1:
The number 974 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 974

Going ahead to step 2:
The number 974 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 974

Let's proceed to step 3:
155 divided by 974 is 0 with a remainder of 155.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 155 to get 155.
Bring next digit (0) of the dividend behind the 155 and repeat the process: 1550 / 974

Let's proceed to step 4:
974 can be fit into 1550 1 times, resulting in a remainder of 576.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 974 from 1550 and we're left with 576.
Grab the next digit (5) from the dividend, add it to 576, then carry on: 5765 / 974

Advancing to step 5:
The number 974 fits into 5765 5 times, leaving a remainder of 895.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
The remainder is 895 after subtracting 4870 from 5765.
Bring next digit (5) of the dividend behind the 895 and repeat the process: 8955 / 974

Let's proceed to step 6:
When dividing 8955 by 974, we get 9 with a remainder of 189.
Write down 9 as next digit of the result. 
Result so far: 159.0
If we take 8766 away from 8955, we end up with 189.
Include the next digit (5) from the dividend after 189, then repeat: 1895 / 974

Step 7:
974 goes into 1895 1 times with a remainder of 921.
Put 1 as the next digit of the answer. 
Result so far: 1591.0
Deduct 974 from 1895 and we're left with 921.
Take the next digit (0) from the dividend and append it to 921, then repeat: 9210 / 974

On to step 8:
When dividing 9210 by 974, we get 9 with a remainder of 444.
The next digit of our result is 9. 
Result so far: 15919.0
The remainder is 444 after subtracting 8766 from 9210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Advancing to step 9:
4440 divided by 974 is 4 with a remainder of 544.
Use 4 as the next digit of our solution. 
Result so far: 15919.4
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.

Step 10:
The number 974 fits into 5440 5 times, leaving a remainder of 570.
Record the quotient 5 as the next digit in the result. 
Result so far: 15919.45
If we subtract 4870 from 5440, we get 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 11:
If we divide 5700 by 974, we get 5 and a remainder of 830.
Record the quotient 5 as the next digit in the result. 
Result so far: 15919.455
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.

The final result is 15919.455 with a remainder of 0.083.
