We look at the division of 91646837 by 426 
Let's see how many times 426 fits into 91646837.

Advancing to step 1:
If we divide 9 by 426, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 426

Let's proceed to step 2:
When dividing 91 by 426, we get 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Include the next digit (6) from the dividend after 91, then repeat: 916 / 426

Going ahead to step 3:
916 divided by 426 is 2 with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 852 from 916, we get 64.
Take the next digit (4) from the dividend and append it to 64, then repeat: 644 / 426

Advancing to step 4:
When dividing 644 by 426, we get 1 with a remainder of 218.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtracting 426 from 644 leaves us with 218.
Include the next digit (6) from the dividend after 218, then repeat: 2186 / 426

Let's proceed to step 5:
The number 426 fits into 2186 5 times, leaving a remainder of 56.
The number 5 becomes the next digit in our result. 
Result so far: 215.0
If we subtract 2130 from 2186, we get 56.
Bring next digit (8) of the dividend behind the 56 and repeat the process: 568 / 426

Let's proceed to step 6:
The number 426 fits into 568 1 times, leaving a remainder of 142.
The next digit of our result is 1. 
Result so far: 2151.0
If we take 426 away from 568, we end up with 142.
Include the next digit (3) from the dividend after 142, then repeat: 1423 / 426

Let's proceed to step 7:
1423 divided by 426 is 3 with a remainder of 145.
Write down 3 as next digit of the result. 
Result so far: 21513.0
Subtracting 1278 from 1423 leaves us with 145.
Bring next digit (7) of the dividend behind the 145 and repeat the process: 1457 / 426

Going ahead to step 8:
1457 divided by 426 is 3 with a remainder of 179.
The next digit of our result is 3. 
Result so far: 215133.0
If we subtract 1278 from 1457, we get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Moving on to step 9:
When dividing 1790 by 426, we get 4 with a remainder of 86.
Use 4 as the next digit of our solution. 
Result so far: 215133.4
If we take 1704 away from 1790, we end up 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 10:
The number 426 fits into 860 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 215133.42
If we subtract 852 from 860, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
80 divided by 426 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 215133.42
Subtract 0 from 80 to 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 12:
The number 426 fits into 800 1 times, leaving a remainder of 374.
Write down 1 as next digit of the result. 
Result so far: 215133.4201
Deduct 426 from 800 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

On to step 13:
When dividing 3740 by 426, we get 8 with a remainder of 332.
The number 8 becomes the next digit in our result. 
Result so far: 215133.42018
Subtracting 3408 from 3740 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

On to step 14:
3320 divided by 426 is 7 with a remainder of 338.
Put 7 as the next digit of the answer. 
Result so far: 215133.420187
Subtract 2982 from 3320 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Moving on to step 15:
426 can be fit into 3380 7 times, resulting in a remainder of 398.
Use 7 as the next digit of our solution. 
Result so far: 215133.4201877
If we subtract 2982 from 3380, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

The final result is 215133.4201877 with a remainder of 3.98e-06.
