We're dividing 20913390 by 974 
Let's see how many times 974 fits into 20913390.

Going ahead to step 1:
When dividing 2 by 974, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 974

Going ahead to step 2:
When dividing 20 by 974, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 974

Going ahead to step 3:
974 goes into 209 0 times with a remainder of 209.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 209, we end up with 209.
Grab the next digit (1) from the dividend, add it to 209, then carry on: 2091 / 974

Step 4:
When dividing 2091 by 974, we get 2 with a remainder of 143.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1948 from 2091, we get 143.
Include the next digit (3) from the dividend after 143, then repeat: 1433 / 974

Moving on to step 5:
If we divide 1433 by 974, we get 1 and a remainder of 459.
Put 1 as the next digit of the answer. 
Result so far: 21.0
The remainder is 459 after subtracting 974 from 1433.
Grab the next digit (3) from the dividend, add it to 459, then carry on: 4593 / 974

Moving on to step 6:
When dividing 4593 by 974, we get 4 with a remainder of 697.
The number 4 becomes the next digit in our result. 
Result so far: 214.0
The remainder is 697 after subtracting 3896 from 4593.
Include the next digit (9) from the dividend after 697, then repeat: 6979 / 974

Going ahead to step 7:
The number 974 fits into 6979 7 times, leaving a remainder of 161.
Write down 7 as next digit of the result. 
Result so far: 2147.0
Subtracting 6818 from 6979 leaves us with 161.
Take the next digit (0) from the dividend and append it to 161, then repeat: 1610 / 974

On to step 8:
1610 divided by 974 is 1 with a remainder of 636.
The number 1 becomes the next digit in our result. 
Result so far: 21471.0
The remainder is 636 after subtracting 974 from 1610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Step 9:
974 can be fit into 6360 6 times, resulting in a remainder of 516.
Put 6 as the next digit of the answer. 
Result so far: 21471.6
Deduct 5844 from 6360 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Moving on to step 10:
When dividing 5160 by 974, we get 5 with a remainder of 290.
Use 5 as the next digit of our solution. 
Result so far: 21471.65
The remainder is 290 after subtracting 4870 from 5160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 11:
The number 974 fits into 2900 2 times, leaving a remainder of 952.
Write down 2 as next digit of the result. 
Result so far: 21471.652
Subtracting 1948 from 2900 leaves us with 952.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9520, and continue the process.

Moving on to step 12:
The number 974 fits into 9520 9 times, leaving a remainder of 754.
The number 9 becomes the next digit in our result. 
Result so far: 21471.6529
Subtract 8766 from 9520 to get 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

Step 13:
If we divide 7540 by 974, we get 7 and a remainder of 722.
Record the quotient 7 as the next digit in the result. 
Result so far: 21471.65297
If we subtract 6818 from 7540, we get 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Moving on to step 14:
7220 divided by 974 is 7 with a remainder of 402.
Write down 7 as next digit of the result. 
Result so far: 21471.652977
If we subtract 6818 from 7220, we get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

The final outcome is 21471.652977, with a leftover of 4.02e-05.
