We look at the division of 91709131 by 428 
We're looking to find how many times 428 goes into 91709131.

Moving on to step 1:
428 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 428

Step 2:
428 goes into 91 0 times with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Fetch the next digit (7) from the dividend, attach it to 91 and continue: 917 / 428

Step 3:
428 can be fit into 917 2 times, resulting in a remainder of 61.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 856 from 917, we get 61.
Grab the next digit (0) from the dividend, add it to 61, then carry on: 610 / 428

Step 4:
If we divide 610 by 428, we get 1 and a remainder of 182.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 428 from 610 to get 182.
Include the next digit (9) from the dividend after 182, then repeat: 1829 / 428

Step 5:
428 goes into 1829 4 times with a remainder of 117.
Use 4 as the next digit of our solution. 
Result so far: 214.0
Subtracting 1712 from 1829 leaves us with 117.
Include the next digit (1) from the dividend after 117, then repeat: 1171 / 428

Moving on to step 6:
If we divide 1171 by 428, we get 2 and a remainder of 315.
Write down 2 as next digit of the result. 
Result so far: 2142.0
If we take 856 away from 1171, we end up with 315.
Take the next digit (3) from the dividend and append it to 315, then repeat: 3153 / 428

Let's proceed to step 7:
428 goes into 3153 7 times with a remainder of 157.
The next digit of our result is 7. 
Result so far: 21427.0
Deduct 2996 from 3153 and we're left with 157.
Append the next digit (1) from the dividend to 157 and continue with: 1571 / 428

Step 8:
1571 divided by 428 is 3 with a remainder of 287.
The number 3 becomes the next digit in our result. 
Result so far: 214273.0
Deduct 1284 from 1571 and we're left with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

On to step 9:
When dividing 2870 by 428, we get 6 with a remainder of 302.
Use 6 as the next digit of our solution. 
Result so far: 214273.6
If we take 2568 away from 2870, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 10:
If we divide 3020 by 428, we get 7 and a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 214273.67
If we take 2996 away from 3020, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
428 goes into 240 0 times with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 214273.67
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 12:
If we divide 2400 by 428, we get 5 and a remainder of 260.
Record the quotient 5 as the next digit in the result. 
Result so far: 214273.6705
If we subtract 2140 from 2400, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 13:
2600 divided by 428 is 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 214273.67056
Subtract 2568 from 2600 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
If we divide 320 by 428, we get 0 and a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 214273.67056
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 15:
3200 divided by 428 is 7 with a remainder of 204.
The number 7 becomes the next digit in our result. 
Result so far: 214273.6705607
If we subtract 2996 from 3200, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 16:
When dividing 2040 by 428, we get 4 with a remainder of 328.
Use 4 as the next digit of our solution. 
Result so far: 214273.67056074
If we subtract 1712 from 2040, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The quotient of the division is 214273.67056074, and the remainder is 3.28e-07.
