Let's divide 21070 by 37
We're looking to find how many times 37 goes into 21070.

Going ahead to step 1:
37 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 37

Going ahead to step 2:
37 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 37

Moving on to step 3:
If we divide 210 by 37, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 185 from 210, we get 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 37

Let's proceed to step 4:
37 can be fit into 257 6 times, resulting in a remainder of 35.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Deduct 222 from 257 and we're left with 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 37

Step 5:
When dividing 350 by 37, we get 9 with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 569.0
Deduct 333 from 350 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 6:
37 can be fit into 170 4 times, resulting in a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 569.4
The remainder is 22 after subtracting 148 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
If we divide 220 by 37, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 569.45
If we subtract 185 from 220, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
37 goes into 350 9 times with a remainder of 17.
The next digit of our result is 9. 
Result so far: 569.459
If we subtract 333 from 350, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
37 goes into 170 4 times with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 569.4594
Subtracting 148 from 170 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
When dividing 220 by 37, we get 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 569.45945
If we subtract 185 from 220, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 11:
37 can be fit into 350 9 times, resulting in a remainder of 17.
The next digit of our result is 9. 
Result so far: 569.459459
Subtracting 333 from 350 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 12:
When dividing 170 by 37, we get 4 with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 569.4594594
The remainder is 22 after subtracting 148 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
The number 37 fits into 220 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 569.45945945
If we take 185 away from 220, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 569.45945945 with a remaining 3.5e-08.
