Let's divide 21235978 by 970
We want to divide 21235978 by 970.

On to step 1:
When dividing 2 by 970, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 970

Let's proceed to step 2:
If we divide 21 by 970, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 970

Advancing to step 3:
970 can be fit into 212 0 times, resulting in a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 212 to get 212.
Append the next digit (3) from the dividend to 212 and continue with: 2123 / 970

Step 4:
2123 divided by 970 is 2 with a remainder of 183.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1940 from 2123 to get 183.
Grab the next digit (5) from the dividend, add it to 183, then carry on: 1835 / 970

Advancing to step 5:
The number 970 fits into 1835 1 times, leaving a remainder of 865.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 970 from 1835 and we're left with 865.
Take the next digit (9) from the dividend and append it to 865, then repeat: 8659 / 970

Let's proceed to step 6:
970 can be fit into 8659 8 times, resulting in a remainder of 899.
Write down 8 as next digit of the result. 
Result so far: 218.0
If we take 7760 away from 8659, we end up with 899.
Take the next digit (7) from the dividend and append it to 899, then repeat: 8997 / 970

Let's proceed to step 7:
8997 divided by 970 is 9 with a remainder of 267.
The next digit of our result is 9. 
Result so far: 2189.0
The remainder is 267 after subtracting 8730 from 8997.
Append the next digit (8) from the dividend to 267 and continue with: 2678 / 970

Advancing to step 8:
970 can be fit into 2678 2 times, resulting in a remainder of 738.
Use 2 as the next digit of our solution. 
Result so far: 21892.0
The remainder is 738 after subtracting 1940 from 2678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Let's proceed to step 9:
970 goes into 7380 7 times with a remainder of 590.
Use 7 as the next digit of our solution. 
Result so far: 21892.7
Deduct 6790 from 7380 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Let's proceed to step 10:
970 goes into 5900 6 times with a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 21892.76
If we subtract 5820 from 5900, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
970 can be fit into 800 0 times, resulting in a remainder of 800.
The next digit of our result is 0. 
Result so far: 21892.76
If we subtract 0 from 800, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 12:
When dividing 8000 by 970, we get 8 with a remainder of 240.
Put 8 as the next digit of the answer. 
Result so far: 21892.7608
If we subtract 7760 from 8000, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 13:
970 goes into 2400 2 times with a remainder of 460.
Use 2 as the next digit of our solution. 
Result so far: 21892.76082
If we subtract 1940 from 2400, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 14:
When dividing 4600 by 970, we get 4 with a remainder of 720.
The number 4 becomes the next digit in our result. 
Result so far: 21892.760824
Subtracting 3880 from 4600 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 15:
The number 970 fits into 7200 7 times, leaving a remainder of 410.
The next digit of our result is 7. 
Result so far: 21892.7608247
Subtract 6790 from 7200 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 16:
4100 divided by 970 is 4 with a remainder of 220.
Put 4 as the next digit of the answer. 
Result so far: 21892.76082474
If we subtract 3880 from 4100, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Our division results in 21892.76082474 with a remaining 2.2e-07.
