We're dividing 1521730 by 157 
We want to figure out the number of times 1521730 can be divided by 157.

Let's proceed to step 1:
157 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 157

On to step 2:
If we divide 15 by 157, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 157

Step 3:
If we divide 152 by 157, we get 0 and a remainder of 152.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 152 leaves us with 152.
Append the next digit (1) from the dividend to 152 and continue with: 1521 / 157

Let's proceed to step 4:
1521 divided by 157 is 9 with a remainder of 108.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 1413 from 1521 leaves us with 108.
Grab the next digit (7) from the dividend, add it to 108, then carry on: 1087 / 157

Advancing to step 5:
The number 157 fits into 1087 6 times, leaving a remainder of 145.
Use 6 as the next digit of our solution. 
Result so far: 96.0
Subtracting 942 from 1087 leaves us with 145.
Fetch the next digit (3) from the dividend, attach it to 145 and continue: 1453 / 157

Let's proceed to step 6:
157 can be fit into 1453 9 times, resulting in a remainder of 40.
The next digit of our result is 9. 
Result so far: 969.0
Subtract 1413 from 1453 to get 40.
Include the next digit (0) from the dividend after 40, then repeat: 400 / 157

On to step 7:
If we divide 400 by 157, we get 2 and a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 9692.0
Deduct 314 from 400 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 8:
When dividing 860 by 157, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 9692.5
Subtracting 785 from 860 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 9:
The number 157 fits into 750 4 times, leaving a remainder of 122.
The number 4 becomes the next digit in our result. 
Result so far: 9692.54
If we take 628 away from 750, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 10:
The number 157 fits into 1220 7 times, leaving a remainder of 121.
Put 7 as the next digit of the answer. 
Result so far: 9692.547
If we subtract 1099 from 1220, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 11:
The number 157 fits into 1210 7 times, leaving a remainder of 111.
Use 7 as the next digit of our solution. 
Result so far: 9692.5477
The remainder is 111 after subtracting 1099 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

The quotient of the division is 9692.5477, and the remainder is 0.00111.
