We're dividing 90021700 by 207 
We're looking to find how many times 207 goes into 90021700.

Moving on to step 1:
9 divided by 207 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 207

Moving on to step 2:
90 divided by 207 is 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Append the next digit (0) from the dividend to 90 and continue with: 900 / 207

Step 3:
900 divided by 207 is 4 with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 828 away from 900, we end up with 72.
Grab the next digit (2) from the dividend, add it to 72, then carry on: 722 / 207

Moving on to step 4:
207 can be fit into 722 3 times, resulting in a remainder of 101.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
If we subtract 621 from 722, we get 101.
Grab the next digit (1) from the dividend, add it to 101, then carry on: 1011 / 207

Going ahead to step 5:
When dividing 1011 by 207, we get 4 with a remainder of 183.
Record the quotient 4 as the next digit in the result. 
Result so far: 434.0
If we subtract 828 from 1011, we get 183.
Grab the next digit (7) from the dividend, add it to 183, then carry on: 1837 / 207

Advancing to step 6:
1837 divided by 207 is 8 with a remainder of 181.
Use 8 as the next digit of our solution. 
Result so far: 4348.0
The remainder is 181 after subtracting 1656 from 1837.
Bring next digit (0) of the dividend behind the 181 and repeat the process: 1810 / 207

Advancing to step 7:
207 can be fit into 1810 8 times, resulting in a remainder of 154.
The next digit of our result is 8. 
Result so far: 43488.0
Subtracting 1656 from 1810 leaves us with 154.
Include the next digit (0) from the dividend after 154, then repeat: 1540 / 207

Moving on to step 8:
207 goes into 1540 7 times with a remainder of 91.
Write down 7 as next digit of the result. 
Result so far: 434887.0
Deduct 1449 from 1540 and we're left with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 9:
The number 207 fits into 910 4 times, leaving a remainder of 82.
Record the quotient 4 as the next digit in the result. 
Result so far: 434887.4
If we subtract 828 from 910, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 10:
If we divide 820 by 207, we get 3 and a remainder of 199.
The number 3 becomes the next digit in our result. 
Result so far: 434887.43
The remainder is 199 after subtracting 621 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Advancing to step 11:
207 can be fit into 1990 9 times, resulting in a remainder of 127.
The next digit of our result is 9. 
Result so far: 434887.439
If we subtract 1863 from 1990, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 12:
207 goes into 1270 6 times with a remainder of 28.
The next digit of our result is 6. 
Result so far: 434887.4396
Subtract 1242 from 1270 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
If we divide 280 by 207, we get 1 and a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 434887.43961
The remainder is 73 after subtracting 207 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 14:
If we divide 730 by 207, we get 3 and a remainder of 109.
Record the quotient 3 as the next digit in the result. 
Result so far: 434887.439613
If we subtract 621 from 730, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 15:
When dividing 1090 by 207, we get 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 434887.4396135
Subtracting 1035 from 1090 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 16:
207 goes into 550 2 times with a remainder of 136.
Write down 2 as next digit of the result. 
Result so far: 434887.43961352
Subtract 414 from 550 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The quotient of the division is 434887.43961352, and the remainder is 1.36e-07.
