We look at the division of 59970426 by 991 
We're looking to find how many times 991 goes into 59970426.

On to step 1:
When dividing 5 by 991, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 991

Going ahead to step 2:
991 can be fit into 59 0 times, resulting in a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 59, we get 59.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 991

Going ahead to step 3:
The number 991 fits into 599 0 times, leaving a remainder of 599.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 599 leaves us with 599.
Grab the next digit (7) from the dividend, add it to 599, then carry on: 5997 / 991

Going ahead to step 4:
991 goes into 5997 6 times with a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 51 after subtracting 5946 from 5997.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 991

Moving on to step 5:
510 divided by 991 is 0 with a remainder of 510.
The next digit of our result is 0. 
Result so far: 60.0
The remainder is 510 after subtracting 0 from 510.
Bring next digit (4) of the dividend behind the 510 and repeat the process: 5104 / 991

Moving on to step 6:
991 goes into 5104 5 times with a remainder of 149.
Write down 5 as next digit of the result. 
Result so far: 605.0
Subtracting 4955 from 5104 leaves us with 149.
Fetch the next digit (2) from the dividend, attach it to 149 and continue: 1492 / 991

Let's proceed to step 7:
991 can be fit into 1492 1 times, resulting in a remainder of 501.
The number 1 becomes the next digit in our result. 
Result so far: 6051.0
Subtract 991 from 1492 to get 501.
Grab the next digit (6) from the dividend, add it to 501, then carry on: 5016 / 991

Step 8:
The number 991 fits into 5016 5 times, leaving a remainder of 61.
The number 5 becomes the next digit in our result. 
Result so far: 60515.0
If we subtract 4955 from 5016, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 9:
If we divide 610 by 991, we get 0 and a remainder of 610.
Record the quotient 0 as the next digit in the result. 
Result so far: 60515.0
Subtract 0 from 610 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Going ahead to step 10:
991 can be fit into 6100 6 times, resulting in a remainder of 154.
Record the quotient 6 as the next digit in the result. 
Result so far: 60515.06
If we subtract 5946 from 6100, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 11:
When dividing 1540 by 991, we get 1 with a remainder of 549.
Use 1 as the next digit of our solution. 
Result so far: 60515.061
Subtracting 991 from 1540 leaves us with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Let's proceed to step 12:
When dividing 5490 by 991, we get 5 with a remainder of 535.
The next digit of our result is 5. 
Result so far: 60515.0615
If we take 4955 away from 5490, we end up with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Going ahead to step 13:
991 can be fit into 5350 5 times, resulting in a remainder of 395.
Put 5 as the next digit of the answer. 
Result so far: 60515.06155
Subtract 4955 from 5350 to get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

The final outcome is 60515.06155, with a leftover of 0.000395.
